摘　　要：新疆阿尔泰的金矿资源类型有岩金矿、伴生金矿和砂金矿.从金矿地质找矿的实用角度,以金矿床的主要地质特征、控矿地质条件及找矿标志为划分依据,将阿尔泰的金矿类型简化为浅成低温热液型、剪切带型及断裂变质带型,其中,浅成低温热液型可细分为火山岩型和微细粒浸染型,剪切带型可细分为破碎蚀变岩型和韧性剪切带型.每一种类型的金矿床具有相应的找矿评价标志.There are three types of gold deposit resource: rock gold,associated gold ore and gold placer,in Altay, Xinjiang.The gold deposit types can be simply classified into epithermal type,shear zone type and rupture-metamorphism type.As the major geological characteristics, controlling-ore geological conditions and exploration indications of the gold deposits from utility for exploration of gold deposits,the epithermal type can also be divided into lava type and minute-granule type. The shear zone type can be divided into fragmented alteration type and ductile shear zone type.Each type of gold deposit has its different exploration indication.
