applied as a method for Structural Health Monitoring for structural damage identification and assessment by tracking the changes of the identified modal parameters over time. Unfortunately, modal parameters also depend on such external factors as temperature and loads. Any structural condition assessment using modal parameters should be done taking into consideration those external factors, otherwise there is a high chance of false positives. A method of structural reliability assessment based on anomaly detection technique called Machalanobis Squared Distance (MSD) is proposed. It requires a set of reference conditions to learn healthy state of a structure, which all future parameters are compared to. In this study, structural modal parameters (natural frequency and mode shape), as well as ambient temperature and loads acting on the structure are used as features. Numerical tests were performed on a finite element model of a carbon fibre reinforced polymer composite beam with delamination damage at various locations and of various severities. The advantages of the demonstrated approach include relatively few computational steps, ability to distinguish between healthy and damaged conditions and discriminate between different damage severities. It is anticipated to be promising in reliability assessment of massively produced structural parts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=operational%20modal%20analysis" title="operational modal analysis">operational modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20assessment" title=" reliability assessment"> reliability assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly%20detection" title=" anomaly detection"> anomaly detection</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=mahalanobis%20squared%20distance" title=" mahalanobis squared distance"> mahalanobis squared distance</a> </p> <a href="https://publications.waset.org/abstracts/148382/a-simple-approach-to-reliability-assessment-of-structures-via-anomaly-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148382.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Petro-Mineralogical Studies of Phosphorite Deposit of Sallopat Block of Banswara District, Rajasthan, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20F.%20Khan">K.

The phosphorites are found to occur as massive, brecciated, laminated and stromatolitic associated with calcareous quartzite, interbedded dolomite and multi coloured chert. The phosphorites are showing alternate brown and grey coloured concentric rims which are composed of phosphate, calcite and quartz minerals. Petro-mineralogical studies of phosphorite samples using petrological microscope, XRD, FEG- SEM and EDX reveal that apatite-(CaF) and apatite-(CaOH) are phosphate minerals which are intermixed with minor amount of carbonate materials. Sporadic findings of the uniform tiny granules of partially anisotropic apatite-(CaF) along with dolomite, calcite, quartz, muscovite, zeolite and other gangue minerals have been observed with the replacement of phosphate material by quartz and carbonate. The presence of microbial filaments of organic matter and alternate concentric rims of stromatolitic structure may suggest that the deposition of the phosphate took place in shallow marine oxidizing environmental conditions leading to the formation of phosphorite layers as primary biogenic precipitates by bacterial or algal activities. Different forms and texture of phosphate minerals may be due to environmental vicissitudes at the time of deposition followed by some replacement processes and biogenic activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apatite" title="apatite">apatite</a>, <a href="https://publications.waset.org/abstracts/search?q=petro-mineralogy" title=" petro-mineralogy"> petro-mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorites" title=" phosphorites"> phosphorites</a>, <a href="https://publications.waset.org/abstracts/search?q=sallopat" title=" sallopat"> sallopat</a>, <a href="https://publications.waset.org/abstracts/search?q=stromatolites" title=" stromatolites"> stromatolites</a> </p> <a href="https://publications.waset.org/abstracts/42417/petro-mineralogical-studies-of-phosphorite-deposit-of-sallopat-block-of-banswara-district-rajasthan-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42417.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Medial Axis Analysis of Valles Marineris</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dan%20James">Dan James</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Medial Axis of the Main Canyon of Valles Marineris is determined geometrically with maximally inscribed discs aligned with the boundaries or rims of the Main Canyon.

As the size of the rims or wheels played an important role in influencing the way of car handles around turns, this paper aims to present the optimality of rim size that drivers should have known while changing their rim. There are three factors that drivers should have considered while changing their rim: rim size, its weight and material of which they are made. Using mathematical analysis, this paper will focus on only one factor, which is rim size. Factors that are considered in calculating the optimum rim size are the vehicle rim radius, tire height and weight, and aspect ratio. This paper has found that there are limitations in percentage change in rim size from the original tire size. Failure to have the right offset size may cause problems in maneuvering the vehicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mathematical%20analysis" title="mathematical analysis">mathematical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20wheel%20size" title=" optimum wheel size"> optimum wheel size</a>, <a href="https://publications.waset.org/abstracts/search?q=percentage%20change" title=" percentage change"> percentage change</a>, <a href="https://publications.waset.org/abstracts/search?q=custom%20wheel" title=" custom wheel"> custom wheel</a> </p> <a href="https://publications.waset.org/abstracts/8523/rim-size-optimization-using-mathematical-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">492</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Opaque Mineralogy of the Late Precambrian Ophiolites from Bou Azzer Area, Anti-atlas, Morrocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Maher%20Abdelaziz%20Hawa">Yaser Maher Abdelaziz Hawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Basic-ultrabasic rocks of Bou Azzer ophiolite complex in the Anti-atlas , Morrocco enclose some oxide and sulfide minerals as dissiminated traces.

Determination of risk factors is essential to plan screening programmes to prevent the disease. To study the demographic risk factors of cervical cancer among Manipuri women, information on age, marital status, educational level, monthly family income and socioeconomic status were collected through a pre-tested interview schedule. In this study, 64 incident cases registered at the RT Dept, RIMS (Regional Institute of Medical Sciences), Imphal, Manipur, India during 2008-09 participated. Data were entered in Microsoft Excel and the results were expressed in percentages. Among the 64 patients with cervical cancer, 56 (88.9%) were in the age group of 40+ years. The majority of the patients were from rural areas (68.75%) and 31.25% were from urban areas. The majority of the patients were Hindus (73%), 55(85.9%) were of low educational level, 43(67.2%) were married, and 36 (56.25%) belonged to Class IV socioeconomic status. In conclusion, if detected early, cervical cancer is preventable and curable. The potential risk factors need to be identified and women in the risk group need to be motivated for screening. Affordable screening programmes and health care resources will help in lessening the burden of the disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title="cervical cancer">cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Manipuri%20women" title=" Manipuri women"> Manipuri women</a>, <a href="https://publications.waset.org/abstracts/search?q=RIIMS" title=" RIIMS"> RIIMS</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-demographic%20risk%20factors" title=" socio-demographic risk factors"> socio-demographic risk factors</a> </p> <a href="https://publications.waset.org/abstracts/63734/sociodemographic-risk-factors-of-cervical-cancer-in-imphal-manipur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63734.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">276</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Analysis and Performance of European Geostationary Navigation Overlay Service System in North of Algeria for GPS Single Point Positioning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tabti%20Lahouaria">Tabti Lahouaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahlouche%20Salem"> Kahlouche Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Benadda%20Belkacem"> Benadda Belkacem</a>, <a href="https://publications.waset.org/abstracts/search?q=Beldjilali%20Bilal"> Beldjilali Bilal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The European Geostationary Navigation Overlay Service (EGNOS) provides an augmentation signal to GPS (Global Positioning System) single point positioning. Presently EGNOS provides data correction and integrity information using the GPS L1 (1575.42 MHz) frequency band. The main objective of this system is to provide a better real-time positioning precision than using GPS only. They are expected to be used with single-frequency code observations. EGNOS offers navigation performance for an open service (OS), in terms of precision and availability this performance gradually degrades as moving away from the service area. For accurate system performance, the service will become less and less available as the user moves away from the EGNOS service. The improvement in position solution is investigated using the two collocated dual frequency GPS, where no EGNOS Ranging and Integrity Monitoring Station (RIMS) exists. One of the pseudo-range was kept as GPS stand-alone and the other was corrected by EGNOS to estimate the planimetric and altimetric precision for different dates. It is found that precision in position improved significantly in the second due to EGNOS correction. The performance of EGNOS system in the north of Algeria is also investigated in terms of integrity. The results show that the horizontal protection level (HPL) value is below 18.25 meters (95%) and the vertical protection level (VPL) is below 42.22 meters (95 %). These results represent good integrity information transmitted by EGNOS for APV I service. This service is thus compliant with the aviation requirements for Approaches with Vertical Guidance (APV-I), which is characterised by 40 m HAL (horizontal alarm limit) and 50 m VAL (vertical alarm limit). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EGNOS" title="EGNOS">EGNOS</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=positioning" title=" positioning"> positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=integrity" title=" integrity"> integrity</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20level" title=" protection level"> protection level</a> </p> <a href="https://publications.waset.org/abstracts/84664/analysis-and-performance-of-european-geostationary-navigation-overlay-service-system-in-north-of-algeria-for-gps-single-point-positioning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84664.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Mineralogy and Thermobarometry of Xenoliths in Basalt from the Chanthaburi-Trat Gem Fields, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apichet%20Boonsoong">Apichet Boonsoong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the Chanthaburi-Trat basalts, xenoliths are composed of essentially ultramafic xenoliths (particularly spinel lherzolite) with a few of an aggregate of feldspar. Some 19 ultramafic xenoliths were collected from 13 different locations. They range in size from 3.5 to 60mm across. Most are weathered and oxidized on the surface but fresh samples are obtained from cut surfaces. Chemical analyses were performed on carbon-coated polished thin sections using a fully automated CAMECA SX-50 electron microprobe (EMPA) in wavelength-dispersive mode. In thin section, they are seen to consist of variable amounts of olivine, clinopyroxene, orthopyroxene with minor spinel and plagioclase, and are classed as lherzolite. Modal compositions of the ultramafic nodules vary with olivine (60-75%), clinopyroxene (20-30%), orthopyroxene (0-15%), minor spinel (1-3%) and plagioclase (<1%). The essential minerals form an equigranular, medium- to coarse-grained, granoblastic texture, and all are in mutual contact indicating attainment of equilibrium. Reaction rims are common along the nodule margins and in some are also present along grain boundaries. Zoning occurs in clinopyroxene, and to a lesser extent in orthopyroxene. The homogeneity of mineral compositions in lherzolite xenoliths suggests the attainment of equilibrium. The equilibration temperatures of these xenoliths are estimated to be in the range of 973 to 1063°C. Pressure estimates are not so easily obtained because no suitable barometer exists for garnet-free lherzolites and so an indirect method was used. The general mineral assemblage of the lherzolite xenoliths and the absence of garnet indicate a pressure range of approximately 12–19kbar, which is equivalent to depths approximately of 38 to 60km. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chanthaburi-trat%20basalts" title="chanthaburi-trat basalts">chanthaburi-trat basalts</a>, <a href="https://publications.waset.org/abstracts/search?q=spinel%20lherzolite" title=" spinel lherzolite"> spinel lherzolite</a>, <a href="https://publications.waset.org/abstracts/search?q=xenoliths" title=" xenoliths"> xenoliths</a>, <a href="https://publications.waset.org/abstracts/search?q=973%20to%201063%C2%B0C" title=" 973 to 1063°C"> 973 to 1063°C</a>, <a href="https://publications.waset.org/abstracts/search?q=38%20to%2060km" title=" 38 to 60km"> 38 to 60km</a> </p> <a href="https://publications.waset.org/abstracts/92834/mineralogy-and-thermobarometry-of-xenoliths-in-basalt-from-the-chanthaburi-trat-gem-fields-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92834.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Ultrastructural Study of Surface Topography of Trematode Parasites of Domestic Buffalo (Bubalus bubalis) in Udaipur, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gayatri%20Swarnakar">Gayatri Swarnakar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paramphistomiasis and fascioliasis diseases have been prevalent due to presence of trematode parasites in the rumen and liver of domestic buffalo (Bubalus bubalis) in Udaipur, India. The trematode parasites such as Paramphistomum cervi, Gastrothylax crumenifer, Cotylophoron cotylophorum, Orthocoelium scoliocoelium, Fasciola hepatica and Fasciola gigantica were collected from infected rumen and liver of the freshly slaughtered buffaloes (Bubalus bubalis) at local zoo abattoir in Udaipur. Live trematodes were washed in normal saline, fixed in 0.2M cacodylate fixative, post fixed in osmium tetraoxide, dehydrated, dried, coated with gold sputter and observed under scanning electronic microscope (SEM). The surface tegument of Paramphistomum cervi was spineless with transverse folds, discontinuous with ridges and grooves. Two types of sensory papillae such as knob like and button shaped were also observed. The oral opening of Cotylophoron cotylophorum was surrounded by wrinkled and ridged tegument which formed concentric elevated rings. Tegument of Cotylophoron cotylophorum in acetabulum region was observed to be rough and bee-comb like structure. Genital sucker of this worm was surrounded by a tyre- shaped elevation of the tegument. Orthocoelium scoliocoelium showed circular and concentric rings of tegumental folds around the oral sucker. Genital pore had knob like papillae with radial tegumental folds. Surface topography of Fasciola gigantica and Fasciola hepatica were found to be rough due to occurrence of different types of spines, three types of sensory papillae, transverse folds and grooves. Oral and ventral suckers were spineless and covered with thick rims of transverse folds. Genital pore showed small scattered spines. Present research work would provide knowledge for ultrastructural characteristics of trematode parasites for chemotherapeutic measures and help us to evolve suitable strategy for the eradication of trematode parasites from the domestic buffalo (Bubalus bubalis). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Domestic%20buffalo" title="Domestic buffalo">Domestic buffalo</a>, <a href="https://publications.waset.org/abstracts/search?q=tegument" title=" tegument"> tegument</a>, <a href="https://publications.waset.org/abstracts/search?q=trematode%20parasites" title=" trematode parasites"> trematode parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrastructure" title=" ultrastructure"> ultrastructure</a> </p> <a href="https://publications.waset.org/abstracts/56120/ultrastructural-study-of-surface-topography-of-trematode-parasites-of-domestic-buffalo-bubalus-bubalis-in-udaipur-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56120.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Diagenesis of the Permian Ecca Sandstones and Mudstones, in the Eastern Cape Province, South Africa: Implications for the Shale Gas Potential of the Karoo Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temitope%20L.%20Baiyegunhi">Temitope L.

Despite the fact that published data gives a vast amount of information on the geology, sedimentology and lithostratigraphy of the Ecca Group in the Karoo Basin of South Africa, little is known of the diagenesis of the potentially feasible shales and sandstones of the Ecca Group. The study aims to provide a general account of the diagenesis of sandstones and mudstone of the Ecca Group. Twenty-five diagenetic textures and structures are identified and grouped into three regimes or stages that include eogenesis, mesogenesis and telogenesis. Clay minerals are the most common cementing materials in the Ecca sandstones and mudstones. Smectite, kaolinite and illite are the major clay minerals that act as pore lining rims and pore-filling cement. Most of the clay minerals and detrital grains were seriously attacked and replaced by calcite. Calcite precipitates locally in pore spaces and partly or completely replaced feldspar and quartz grains, mostly at their margins. Precipitation of cements and formation of pyrite and authigenic minerals as well as little lithification occurred during the eogenesis. This regime was followed by mesogenesis which brought about an increase in tightness of grain packing, loss of pore spaces and thinning of beds due to weight of overlying sediments and selective dissolution of framework grains. Compaction, mineral overgrowths, mineral replacement, clay-mineral authigenesis, deformation and pressure solution structures occurred during mesogenesis. During rocks were uplifted, weathered and unroofed by erosion, this resulted in additional grain fracturing, decementation and oxidation of iron-rich volcanic fragments and ferromagnesian minerals. The rocks of Ecca Group were subjected to moderate-intense mechanical and chemical compaction during its progressive burial. Intergranular pores, matrix micro pores, secondary intragranular, dissolution and fractured pores are the observed pores. The presence of fractured and dissolution pores tend to enhance reservoir quality. However, the isolated nature of the pores makes them unfavourable producers of hydrocarbons, which at best would require stimulation. The understanding of the space and time distribution of diagenetic processes in these rocks will allow the development of predictive models of their quality, which may contribute to the reduction of risks involved in their exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagenesis" title="diagenesis">diagenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20quality" title=" reservoir quality"> reservoir quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecca%20Group" title=" Ecca Group"> Ecca Group</a>, <a href="https://publications.waset.org/abstracts/search?q=Karoo%20Supergroup" title=" Karoo Supergroup"> Karoo Supergroup</a> </p> <a href="https://publications.waset.org/abstracts/100475/diagenesis-of-the-permian-ecca-sandstones-and-mudstones-in-the-eastern-cape-province-south-africa-implications-for-the-shale-gas-potential-of-the-karoo-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Participation of Titanium Influencing the Petrological Assemblage of Mafic Dyke: Salem, South India </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayoti%20Banerjee">Ayoti Banerjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Meenakshi%20Banerjee"> Meenakshi Banerjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of metamorphic reaction textures is important in contributing to our understanding of the evolution of metamorphic terranes. Where preserved, they provide information on changes in the P-T conditions during the metamorphic history of the rock, and thus allow us to speculate on the P-T-t evolution of the terrane. Mafic dykes have attracted the attention of petrologists because they act as window to mantle. This rock represents a mafic dyke of doleritic composition. It is fine to medium grained in which clinopyroxene are enclosed by the lath shaped plagioclase grains to form spectacular ophitic texture. At places, sub ophitic texture was also observed. Grains of pyroxene and plagioclase show very less deformation typically plagioclase showing deformed lamella along with plagioclase-clinopyroxene-phyric granoblastic fabric within a groundmass of feldspar microphenocrysts and Fe–Ti oxides. Both normal and reverse zoning were noted in the plagioclase laths. The clinopyroxene grains contain exsolved phases such as orthopyroxene, plagioclase, magnetite, ilmenite along the cleavage traces and the orthopyroxene lamella form granules in the periphery of the clinopyroxene grains. Garnet corona also develops preferentially around plagioclase at the contact of clinopyroxene, ilmenite or magnetite. Tiny quartz and K-fs grains showed symplectic intergrowth with garnet at a few places. The product quartz formed along with garnet rims the coronal garnet and the reacting clinopyroxene. Thin amphibole corona formed along the periphery of deformed plagioclase and clinopyroxene occur as patches over the magmatic minerals. The amphibole coronas cannot be assigned to a late magmatic stage and are interpreted as reactive being restricted to the contact between clinopyroxene and plagioclase, thus postdating the crystallization of both. The amphibole and garnet do not share grain boundary in the entire rock and is thus pointing towards simultaneous crystallization. Olivine is absent. Spectacular myrmekitic growth of orthoclase and quartz rimming the plagioclase is consistent with the potash metasomatic effects that is also found in other rocks of this region. These textural features are consistent with a phase of ﬂuid induced metamorphism (retrogression). But the appearance of coronal garnet and amphibole exclusive of each other reflects the participation if Ti as the prime reason. Presence of Ti as a reactant phase is a must for amphibole forming reactions whereas it is not so in case of garnet forming reactions although the reactants are the same plagioclase and clinopyroxene in both cases. These findings are well validated by petrographical and textural analysis. In order to obtain balanced chemical reactions that explain formation of amphibole and garnet in the maﬁc dyke rocks a matrix operation technique called Singular Value Decomposition (SVD) was adopted utilizing the measured chemical compositions of the minerals. The computer program C-Space was used for this purpose and the required compositional matrix. Data fed to C-Space was after doing cation-calculation of the oxide percentages obtained from EPMA analysis. The Garnet-Clinopyroxene geothermometer yielded a temperature of 650 degrees Celsius. The Garnet-Clinopyroxene-Plagioclase geobarometer and Al-in amphibole yielded roughly 7.5 kbar pressure. <p class="card-text"><strong>Keywords:</strong> <a
