摘　　要：新疆鄯善县康古尔金矿带小尖山金矿位于星星峡谷带—旱山微板块中的雅满苏-红石山-黑鹰山晚古生代陆内裂谷带内康古尔金矿带的东部,产于苦水大断裂南侧的巨型韧性剪切带内,具有明显韧性剪切带控矿作用。矿体分为2类:蚀变岩型金矿、石英脉型金矿。矿区初步圈定了3条较具规模的蚀变岩型金矿体和2条石英脉型金矿体。其中,蚀变岩型金矿是主要矿床类型,赋存于安山质凝灰岩与英安质凝灰岩的接触带上安山质凝灰岩一侧,整个矿带受苦水断裂之次级韧性剪切带控制。通过综合分析,初步认为该区金矿属于与韧性剪切带有关的中—低温热液型金矿床,并总结了控矿构造、容矿岩石、岩浆岩、地球化学、热液蚀变等5个方面的找矿标志。The Xiaojianshan gold deposit in Shanshan,Xingjiang,is located in the east of the Kanggurtag gold belt which is in the Aqishan Yamansu island arc belt in the northeast of Tarim plate.It is controlled by the ductile shear zone in the south of Kushui large fault.The gold deposit is divided into altered rock type gold deposit and quartz vein type gold deposit.Three gold deposits of the large altered rock type,being occur in the contact zone of andesitic tuff with dacitic tuff,being and two quartz vein type gold deposits have been confirmed.Kanggurtag gold belt is controlled by sub-ductile shear zone of the Kushui large fault and is a middle-lower temperature hydrohhermal deposit.
