SOURCES OF CARBON IN ENDOGENOUS FORMATION S OF THE SORSKOE COPPER-MOLYBDENUM-PORPHYRY DEPOSIT (KUZNETSK-ALATAU)

The Sorskoe Deposit localized within the Uibat granitoid pluton, which is situated among Proterozoic and Cambrian limestone series, is chara cterized by a significant role of CO2 in ore-metasomatic processes. Is otopic composition of carbon of limestones, carbonates from ore format ions, and fluid inclusions points to its delivery from host carbonate- terrigenous series during their thermal-fluid transformation. These se ries (especially their carbonaceous differentiates) might also be one of the sources of molybdenum fluorine, and sulfur. The presence of suc h a source was responsible for the specific features of the Sorskoe De posit (elevated CO2 and F contents), which distinguish it from many ot her copper-molybdenum-porphyry deposits.
