摘　　要：研究区构造范围北起苦水(雅满苏)断裂南到沙泉子断裂,西起库姆塔格沙垄东至甘(肃)、新(疆)边界。地层以下石炭统阿齐山组火山岩和雅满苏组火山沉积岩为主。大地构造被厘定为雅满苏-沙泉子晚古生代裂陷槽。区域矿产受地层(含火山岩)、构造含火山构造(火山穹隆、火山洼地、火山机构)和侵入岩控制。通过研究将矿产划分为3个成矿系统:(1)火山成矿系统,有火山沉积—热水沉积型Cu、Ag、PbZn、Co、Au矿,次火山岩型、热液型Fe、Cu、Au矿与其相关的角岩型、矽卡岩型Cu、Au矿;(2)构造成矿系统,有韧性剪切带型Au矿;(3)岩浆成矿系统,有岩浆型V、Ti磁铁矿(基性岩)和Cu、Ni矿(基性—超基性杂岩)。The structural area of the research region is from the north of the Kushui (Yamansu) fault to the Shaquanzi fault in the south, and from the west of the Kumtag Sandy Ridge to the Gansu (Su) and Xin (Jiang) borders. The strata are mainly volcanic rocks of Lower Carboniferous Aqishan Formation and volcano-sedimentary rocks of Yamansu Formation. The tectonics is defined as Yamansu-Shaquanzi rife of Late Palezoic. Regional ore deposits are controlled by strata (including volcanic rocks), tectonic volcanic structures (volcanic domes, volcanic depressions, volcanic structures) and intrusive rocks. The series of mineralization can be defined for the deposits:①Volcanic mineralization series - volcanic sedimentation - hydrothermal sedimentary Cu, Ag, Pb-Zn, Co, Au orebodies, orebodies of subvolcanic rocks, Fe, Cu, Au orebodies of hydrothermal type and associated angular rock, Cu, Au ore bodies of skarn type; ②Tectonic metallogenic series - Au orebody of ductile shear zone; ③Magmatic metallogenic series - magmatic V, Ti magnetite (basic rocks) and Cu, Ni ore (basic-ultrabasic rock complex).
