The carbonatites are volumetrically minor, and their formation is related to collision between the South China block (SCB) and Qinling orogen, which led to the amalgamation of the NCB and SCB. The carbonatites are intruded into different Archean and Mesoproterozoic wall-rocks, but are characterized by remarkably similar isotopic compositions [(87Sr/86Sr)i = 0.7048–0.7057; εNd = − 4.3 to − 10.1; 207Pb/206Pb = 0.878–0.889 and 208Pb/206Pb = 2.136–2.160], which approach, and trend toward slightly less radiogenic Sr and Nd values than, the enriched mantle component EM1. Proterozoic oceanic crust recycled through deep mantle is interpreted to be the principal source of carbon for the Lesser Qinling carbonatites. In comparison with most other young carbonatites (\u0026amp;amp;lt; 200 Ma) emplaced in a rift setting, the Lesser Qinling suite contains appreciably lower εNd and higher 207Pb/206Pb and 208Pb/206Pb values, which suggest the presence of an isotopically distinct additional component in its mantle source. The Pb isotopic signature of these carbonatites is significantly distinct from that of the Precambrian rocks in the North China block, but is similar to that of basement rocks in the South Qinling. On the basis of the available isotopic, geophysical and tectonic constraints, we suggest that the southern margin of the North China block was underthrust by crustal material derived from the South Qinling during their collision. The underthrusting contributed to thickening of the lower crust beneath the North China block and its conversion to dense eclogite. This process culminated in brittle delamination of the eclogitized material into the mantle and its metasomatic reworking by carbonate-rich melts derived from the EM1-type recycled Proterozoic crust. Carbonate metasomatism could produce an enriched sub-continental lithospheric source capable of yielding a variety of magma types.► Qinling orogenic belt is critical for unraveling the tectonic history of East Asia. ► Sr–Nd–Pb isotopes of carbonatite from northmost Qinling were studied. ► Lower crust of South Qinling was driven and subducted into North China block mantle. ► Carbonate metasomatism could produce an enriched sub-continental lithospheric source.","author":[{"@context":"https://schema.org","@type":"Person","name":"Wenlei

In this work, we present direct geochronological and geochemical evidence for the incorporation of recycled crustal materials in collision-related carbonatites of the South Qinling orogenic belt (SQ), which merges with the Lesser Qinling orogen (LQ) to separate the South and North China Blocks. The SQ carbonatites occur mainly as stock associated with syenites. The data presented here show that zircon from the syenites yields an age of 766 ± 25 Ma, which differs significantly from the age of primary monazite from the carbonatites (233.6 ± 1.7 Ma). The syenites contain lower initial 87Sr/86Sr and higher εNd values. This indicates that the carbonatites do not have genetically related with the silicate rocks, and were directly derived from a primary carbonate magma generated in the mantle. The carbonatites show a Sr–Nd isotopic signature similar to that of the chondritic uniform reservoir (CHUR), and parallel Sm–Nd model ages (TCHUR) of 190–300 Ma. However, the rocks have extremely variable Pb isotopic values straddling between the HIMU and EM1 mantle end-members. Most carbon and oxygen isotopic compositions of the SQ carbonatites plot outside the field for primary igneous carbonates. Their δ13C shows higher value than a ‘normal’ mantle, which implies an incorporation of recycled inorganic carbon. The carbonatites were emplaced close to the Mianlue suture, and followed the closure of the Mianlue ocean and Triassic collision of the South and North China Blocks. However, direct melting of the subducted Mianlue oceanic crust characterized by high εNd and low (EM1-like) 206Pb/204Pb values cannot explain the CHUR-like Nd signature and the Pb isotopic trend toward HIMU in the SQ carbonatites. We conclude that their parental magma was derived from a source incorporating the Mianlue oceanic crust mixed with an asthenospheric (or deeper) material characterized by high Pb and low Nd isotopic values. This material represents a deep-seated Proterozoic carbonate component recycled via mantle convection or localized upwelling. Notably, this model cannot explain the isotopic compositions of the Late Triassic (209–221 Ma) carbonatites in the LQ, characterized by a mantle-derived δ13C, but EM1-like Sr–Nd–Pb isotopic compositions. This signature is best explained in terms of delamination of the lower continental crust thickened during the collision of the South and North China Blocks, and partial incorporation of the delaminated material into the LQ mantle source. Modeling of the measured Sr–Nd–Pb isotopic variations suggests that the source of the LQ carbonatites could be produced by mixing of 80–85% of mantle material and 15–20% of delaminated lower continental crust. The emplacement of the SQ and LQ carbonatites marked a gradual transition from a compressional tectonic regime, brought about by the collision of the South and North China Blocks to intra-orogenic extension in the waning stages of the Triassic orogeny.</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":"Origin of carbonatites in the South Qinling orogen: Implications for crustal recycling and timing of collision between the South and North China Blocks","attachmentId":38130090,"attachmentType":"pdf","work_url":"https://www.academia.edu/13801759/Origin_of_carbonatites_in_the_South_Qinling_orogen_Implications_for_crustal_recycling_and_timing_of_collision_between_the_South_and_North_China_Blocks","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/13801759/Origin_of_carbonatites_in_the_South_Qinling_orogen_Implications_for_crustal_recycling_and_timing_of_collision_between_the_South_and_North_China_Blocks"><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="1" data-entity-id="83034888" 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/83034888/Carbon_Strontium_Isotope_Decoupling_in_Carbonatites_from_Caotan_Qinling_China_Implications_for_the_Origin_of_Calcite_Carbonatite_in_Orogenic_Settings">Carbon–Strontium Isotope Decoupling in Carbonatites from Caotan (Qinling, China): Implications for the Origin of Calcite Carbonatite in Orogenic Settings</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="4251396" href="https://otago.academia.edu/MarcoBrenna">Marco Brenna</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Petrology, 2020</p><p class="ds-related-work--abstract ds2-5-body-sm">Mantle-derived carbonatites emplaced in orogenic belts and some extensional settings are hypothesized to contain recycled crustal material. However, these carbonatites are typically composed of calcite showing a typical mantle range of C–O isotopic values devoid of recognizable sedimentary fingerprints. Here, we report the first known instance of C–Sr isotope decoupling between intimately associated dolomite carbonatites and magnetite–forsterite–calcite carbonatites from the northern Qinling orogen, central China. The calcite-dominant variety is developed at the contact between the dolomite carbonatite and metasomatized wall-rock gneiss. The two types of carbonatites have similar δ18OVSMOW (6·98‰ to 9·96‰), εNd(i) (-3·01 to -6·47) and Pb (206Pb/204Pb(i) = 17·369–17·584, 207Pb/204Pb(i) = 15·443–15·466) isotopic compositions, but
