FLUID INCLUSION STUDY ON THE MOYOULETE Sb-Cu DEPOSIT, ALTAY

摘要

CO_2-rich fluid inclusions in Q1 have Tm,CO_2= - 61.9~ -57.9 °C and Th,CO_2= -10.0~21.6 °C , the Th,tots’ are 358~388 °C, while in Q2 have Tm,CO_2= - 63.2~ -60.2 °C and Th,CO_2= -20.4~17.4°C, the Th,tots’ are 270~325°C in the Moyoulete Sb-Cu deposit. The characteristics of CO_2-rich fluid inclusions from the Moyoulete Sb-Cu deposit are similar to those from other Cu-Au mineralization localities. The genesis of vein Sb-Cu mineralization was connected with the orogeny-metamorphism hydrothermal fluid, resulting from the orogeny metamorphism of the Late Permian-Triassic in the the south margin of the Altay Mountains.
