摘　　要：金窝子矿田控矿构造复杂,成矿条件独特,金矿化类型多样。经研究,金窝子矿田的形成与中天山地块向北山裂谷带逆冲推覆作用有关。逆冲推覆造就了金窝子矿田北、中、南3个不同性质的断裂带及不同的金矿化物理、化学环境,并分别控制了金矿田与其相关的金矿化类型及其成矿作用和金矿成矿系列。The ore-controlling structure of Jinwozi orefield is complex.Its ore-forming condition is unique,and its mineralization type is characterized by diversity.The research results show that the its formation was relevant with the thrusting nappe structure of Middle Tianshan Massif,thrusting nappe to Beishan Rift zone.This thrusting nappe structure resulted in three different fracture zones from north to south and varied physicalchemical enviroment in Jingwozi gold orefield.This also determinates gold mineralization type,metallogenesis and metallogenic series.
