新疆博乐科克赛铜钼矿与花岗闪长斑岩地球化学特征

Geochemical characteristics of copper and molybdenum ore and granodiorite porphyry in Bole, Xinjiang

新疆博乐科克赛花岗闪长斑岩体属华力西中期形成的岩浆侵入体。通过对岩石化学及岩石地球化学的分析研究认为该岩体的岩浆成因类型为壳幔混合型深成花岗岩类,属同造山期地壳熔融形成的"I"型钙碱性岩石系列花岗岩类岩石。据近年发现的与该岩体有关的铜钼矿情况分析,认为该岩体具有寻找铜钼矿的前景。

Granodiorite porphyry in the keersai area,bole city,which intrusive magma formationed in the intermediate stage of Variscian.Through the analytical study of petrochemistry and lithgeochemistry,it is thought that this intrusive magma is hypogene magma,admixed by the magma of earth mantle and earth crust,belong to the same orogenic phase,and the type is“ I” granite （alkali granite）.Bass on the analyse of the lithosome’s molybdenum minerals and copper ore ,it was considered that the lithosome have the foreground of finding molybdenum minerals and copper ore.
