摘要
川西藏东地区在大地构造位置上处于欧亚板块和印度板块结合部位的特提斯构造域东段。自早古生代以来，区内曾经历过多期次的构造岩浆活动，为金的成矿作用提供了十分有利的成矿条件。区内金矿床的主要类型有：火山成因块状硫化物型金矿床、层控型金矿床、浊积岩型金矿床、岩浆期后热液型金矿床、矽卡岩型金矿床、斑岩型金矿床、剪切带型金矿床。
Geotectonically,the studied area lies in the eastern sector of the Tethys which the junction of Eurasian plate and indian plate.Since the Early Paleozoic, multiple tectonic-magmatic activities have occurred, creating favourable conditions for gold ore-formation Gold depodits in the studied area may be didided into 7 types:massive sulfide type, stratabound type,turbidite type, postmagmatic hydrothermal type, sham type,porphyry type and shear zone type.
