Ce complexe granitique de caractère tardi-tectonique (≈ 279 ±6 Ma) a développé une auréole de métamorphisme de contact qui dépasse les 2 km de largeur considéré autant qu’un événement tardif au métamorphisme régional, Ce phénomène est généré dans un encaissant d’âge primaire formé par des quartzites Cambro-ordoviciennes, des schistes gréseux et grauwackes de Namurien et des flysches, calcschistes (skarns). Quatre coupes ont été réalisées dans les parties Nord, Ouest et Sud du massif granitique, avec un prélèvement d’une trentaine d’échantillons au niveau du contact granite-encaissant pour une étude pétrographique détaillée.L’étude microscopique des différents faciès récoltés, ont permis de déterminer deux types de métamorphisme: Le premier est précoce lié au contraintes régionales, ce type de métamorphisme est caractérisé par l’orientation des minéraux liés au granite possédant un plan de la schistosité S1. Le deuxième type de métamorphisme est subséquent à la mise en place définitive du granite, il est caractérisé par la présence des minéraux d’andalousites. non orientés résultant de cette mise en place. Les Paragenèses minérales déterminées par la suite, nous a permis de définir deux principales zones métamorphiques : Zone I à chlorite + muscovite ± biotite et Zone II à andalousite + biotite + muscovite. Au niveau du massif granitique du Ment les activités hydrothermales s’expriment notamment par l’abondance de filons de tourmalines, de greisens qui se concentrent dans les parties Nord et Ouest du massif granitique. Abstract The Hercynian granitic massif of Ment region, is located in central northern Morocco. This granite complex has a late tectonic character (≈ 279 ± 6 Ma) developed a contact metamorphism aureole that exceeds 2 km in width, considered as a late event to regional metamorphism. This phenomenon is generated in an crashing dated on primary age, formed by Cambro-Ordovician quartzites, sandstone schists and grauwackes of Namurian and flysches, calcschistes (skarns). Four geological sections were made in the northern, western and southern parts of the granitic massif, with of thirty samples are sampling at the graniteclay contact for a detailed petrographic study. The microscopic study of the different facies samplied, made it possible to determine two types of metamorphism: The first is early due to regional constraints; this type of metamorphism is characterized by the orientation of granite-bound minerals with a S1 schistosity plane. The second type of metamorphism is subsequent to the definitive implementation of the granite, characterized by the presence of the andalusite minerals resulting from this implementation. The mineral Parageneses determined later, allowed us to define two main metamorphic zones: Zone I with chlorite + muscovite ± biotite and Zone II with andalusite + biotite +muscovite. At the level of the granitic massif of Ment, hydrothermal activities are expressed in particular by the abundance of veins of tourmalines, greisens which are concentrated in the northern and western parts of the granite massif.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Etude de l'auréole de métamorphisme de contact du granite hercynien du Ment (Maroc Central)","attachmentId":55251284,"attachmentType":"pdf","work_url":"https://www.academia.edu/35391248/Etude_de_laur%C3%A9ole_de_m%C3%A9tamorphisme_de_contact_du_granite_hercynien_du_Ment_Maroc_Central_","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/35391248/Etude_de_laur%C3%A9ole_de_m%C3%A9tamorphisme_de_contact_du_granite_hercynien_du_Ment_Maroc_Central_"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="4628421" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/4628421/P%C3%A9trographie_et_g%C3%A9ochimie_du_massif_granitique_tardi_hercynien_dAlouana_Boutonni%C3%A8re_de_Debdou_Maroc_Nord_Oriental_">Pétrographie et géochimie du massif granitique tardi-hercynien dAlouana (Boutonnière de Debdou, Maroc Nord Oriental)</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="950954" href="https://fldm-usmba.academia.edu/AbdellahBoushaba">Abdellah Boushaba</a></div><p class="ds-related-work--abstract ds2-5-body-sm">Abstract:The Alouana granitic pluton, Stephanian in age (284t7 M.a ;Tisseranl,1977), intrudes a thick sequence of Devonian schists (Givetian-FrasniaÀy, folded and weakly metamorphosed. lts shape is elliptical with a NW-SE trending long axis, 6 km long, and a short axis, 3.5 km lông, NE-SW trending. The emplacement of the granite leads to the development of a contact metamorphism aureole, of decreasinj intensity away from the pluton. The Alouana granite, of calc-alkaline affinity, is associated to microgranite dykes, aplitic and pelmatitic, éutting through the intrusive body as well as the metamorphic host rocks. The Alouana pluton shows three petrographic facies with a gross concentric distribution; these are: - a central equigranular facies, with medium to coarse grain size; - an intermediate heterogranular facies with fine to medium grain size; - a peripheral microgranitic facies. These petrographic variations are associated to textural and mineralogical differences, which leads us to distinguish two facies: principal granite at coarse grain and at biotite dominant and a secondary facies at finer grain and at muscovite. As a whole the granitic facies at Alouana show a mineralogy dominated by quartz (20-45%), plagioclase (15'40%\ K-feldspar (1S-35%), biotite (3-11%) and muscovite (<1-7o/o). Accessory minerals are tourmaline, apatite, zircon and..allanite. ln terms of geoènemistiy, the Alouana granite can be defined a meta- to peraluminous granite (normative corundum)with a calc-alkaline affinity. Hydrothermal alteration leads mostly to an albitisation of plagioclase and a more or less advanced greisenisation. The emplacement of the Alouana granitic massif leads to a polyphased contact metamorphism. This metamorphism is mostly associated to the recristallisation of bio[ite l, cordierite+/- andalusite within Sr, and that of biotite ll and andalusite ll within 53, contemporaneous with P3 folding stage.

Résumé: Dans la partie orientale du Massif Hercynien Central Marocain, des sills sont interstratifiés au sein des formations du Carbonifère supérieur du bassin méridional d'Azrou-Khénifra. Mis en place parallèlement à la stratification, ces sills sont déformés avec leur encaissant par des plis associés aux chevauchements contrôlant la sédimentation, ce qui démontre leur caractère syntectonique. I-eur composition chimique permet de distinguer deux ensembles magmatiques interstratifiés dans deux séries sédimentaires qui se succèdent dans le temps: la série de Tanwalt datée V3b et la série de Talgarat d'âge V3c-Namurien probable. Le premier ensemble magmatique englobe des roches basiques à caractère transitionnel et une affinité alcaline, tandis que le deuxième renferme des roches à caractèie calco-alcalin. Ces deux ensembles, montrant d'étroites relations pétrographiques, présentent plusieurs similitudes géochimiques avec les séries magmatiques des zones de marges actives. Les signatures géochimiques et l'évolution maginatique de ces roches sont compatibles avec les données tectono-sédimentaires qui caractérisent le bassin d'Azrou-Khénifra, comme un bassin en coinpression, s'intégrant dans le système d'avanrpays déterminé par des séquences de chevauchements se propageant vers le NW. Key-words: Hercynien chain, Morocan meseta, Foreland basin, Active margins. Abstract: In the eastern part of the Central Hercynian Massif of Morocco, some sills are interbeded with the Upper Carboniferous formations of the southern basin ofAzrou-Khénifra. These sills displays the same folds and overthrusts that observed in the surrounding sedimentary beds, a fact that demonstrates their syntectonic character. Their chemical composition allows the distinction of two different magmatic sequences superposed in the sedimentary Tanwalt and Talgarat series, respectively of V3b and probably of Namurian-V3c ages. The first magmatic set includes basic rocks with an transitional character and alkaline affinity, whereas the second contains rocks with a calc-alkaline signature. These two sets, showing close relationships, present several geochemical similitudes with those ofactive margin zones. The geochemical signatures and the magmatic evolution of these rocks are compatibles, such as the tectono-sedimentary data who characterise the basin of Azrou-Khénifra, as generated in a compressive regime of a foreland basin system which was determined by a sequence of overlapping propagating NW sense. Palav ras-chave : Cadeia hercfnica, meseta marroquina, margem activa. Resumo: Naparte orientâl do Maciço Hercinico Central de Marrocos afloram alguns filôes intercalados em formaçôes do CarMnico superior do Sudeste da bacia de Azrou-Kénifra. Estes lilôes instalaram-se paralelamente à estratificaçâo e foram deformados por dobramentos associados aos cavalgamentos que controlatam a sedimentaçâo, o que demonstra o seu carâcter sintectônico. A sua composiçâo quimica permitiu distinguir dois tipos de sequências magmâticas sobrepostas nas séries de Tanwalt e Talgarat, respectivamente de idades V3b e Namuriano-V3c, provâvel. A primeira inclui rochas bâsicas de carâcter transicional e afinidade alcalina, enquanto a segunda possui uma assinatura calco-alcalina. Estas sequências magm6ticas âpresentam estreitas semelhanças petrogrâhcas e geoquimicas com as que ocorrem em ambientes de margem activa. As assinaturas geoquimicas e a evoluçâo magmâtica destas rochas sâo compativeis com os dados tectono-sedimentares que cæacterizam a bacia de Azrou-Kénifra como uma bacia desenvolvida em regime compressivo, integada num sistema de "avant pays" determinado por sequências de cavalgamentos propagando-se para NW.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Le magmatisme terminal de la chaîne hercynienne: signification géodynamique d'une association magmatique identifiée dans le Carbonifère terminal du Massif Hercynien Central Marocain","attachmentId":33171302,"attachmentType":"pdf","work_url":"https://www.academia.edu/6344534/Le_magmatisme_terminal_de_la_cha%C3%AEne_hercynienne_signification_g%C3%A9odynamique_dune_association_magmatique_identifi%C3%A9e_dans_le_Carbonif%C3%A8re_terminal_du_Massif_Hercynien_Central_Marocain","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/6344534/Le_magmatisme_terminal_de_la_cha%C3%AEne_hercynienne_signification_g%C3%A9odynamique_dune_association_magmatique_identifi%C3%A9e_dans_le_Carbonif%C3%A8re_terminal_du_Massif_Hercynien_Central_Marocain"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="4" data-entity-id="19415817" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/19415817/S%C3%A9dimentation_d%C3%A9tritique_continentale_synchrone_dun_volcanisme_explosif_dans_le_Trias_terminal_%C3%A0_infra_Lias_du_domaine_atlasique_Haute_Moulouya_Maroc_Late_Triassic_to_infra_Liassic_continental_detrital_sedimentation_synchronous_with_an_explosive_volcanic_event_in_the_Atlas_area_Hgh_Moulouya_">Sédimentation détritique continentale synchrone d'un volcanisme explosif dans le Trias terminal à infra-Lias du domaine atlasique (Haute Moulouya, Maroc) (Late Triassic to infra-Liassic continental detrital sedimentation synchronous with an explosive volcanic event in the Atlas area [Hgh Moulouya...</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="39618421" href="https://univ-lorraine.academia.edu/FChalotprat">Francoise Chalot-Prat</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of African Earth Sciences, 2000</p><p class="ds-related-work--abstract ds2-5-body-sm">subaquatiques de projections volcaniques, a ete mise en evidence dans un bassin intracontinental, decakilometrique et allonge suivant une direction SW-NE.

Dans I'axe subsident, correspondant a la partie meridionale du bassin, la sedimentation est globalement organisee en une mesosequence hectometrique positive avec de bas en haut: un conglomerat grossier de base de cone de Piedmont; des depots fluviatiles relativement moins grossiers organises en chenaux conglomeratiques et depots de decantation de plaines d'inondation; une sedimentation silto-argileuse et carbonatee renfermant des fragments basaltiques d'origine pyroclastique.
