摘　　要：乔尕山花岗岩体的矿物学、地球化学、同位素等特征研究表明它是东天山地区晚古生代陆内俯冲、挤压、推覆等构造作用，发生重熔改造的产物，且受到后期强烈的韧性剪切作用，流体－岩石作用也相当明显．该岩体的形成、演化及后期的地质作用对该区金矿的形成有着内在的联系．The studies of mineralogy,geochemistry and isotope show that Qiaogashan granite derived from the sedimentary strata remelting and deforming due to the late Palaeozoic intracontinental subduction, layer slip, nappe,etc. in East Tianshan mountain. The stock was influenced by the late period strong ductile shearing, and also reacted by fluid rock reaction obviously. The forming, evolution of the stock and the effect of later geological event are associated with the formation of gold deposit in this area.
