康古尔地区金矿成因类型及其控矿因素

新疆康古尔地区地质、构造复杂、成矿条件独特，是以金为主的多金属矿成矿有利地段。金矿成因类型多样，有韧性剪切带型、超浅成低温火山－水热型、中低温火山水热型、中低温岩浆－水热型等。剪切带型金矿是本区主要成矿类型。大地构造、地层岩性、侵入岩、火山岩和韧性剪切带等均与金矿形成有着密切关系。中酸性火山岩是本区主要成矿母岩，韧－脆性剪切带是金矿形成的重要导矿构造。成矿物质来源于上地幔和下地壳。主要成矿时代为晚

GENESIS TYPES OF GOLD EDPOSIT AND THEIR ORE CONTROLLING FACTORS IN KANGGURTAG REGION

The geological and tectonic background of Kanggur region of Xinjiang is complex, the matallogenic condition is unique. It is a favourable region for the gold dominated multimetal metallogenesis.The genesis type Of gold deposit is diversified, which has ductile shear zone. type, ultra-hypergenetic low temperature volcanic- hydrothermal type, low intermediate temperature volcanin-hydrothermal type, low-intermediate temperature magma hydrothermal type.The ductile shear zone type is the dominant metallogenic type.There is a closely retationship between the formation of gold deposit and the tectonics, stratigraphy, petrological character, intrusive rocks, Uol canic rocks ands ductile shear zone. The intermediate-acid volcanic rock is the main metallogenic mother rock. the ductile-brittle shear zone is the important ore conducting structure for the formation of gold deposit.The metallogenic source material comes from the upper mantle and the lower crust. The key metallogenic stage is Late Carboniferous-Early Permian. Mahuanggou-Matoutan, Qishitan and Shiyingtan are the main prospect regions for gold metallogenesis and prospecting.
