摘要
新疆北山地区金矿床（点）为中低温浅成矿床，其矿化类型有准绿片岩型、破碎蚀变岩型、基性侵入体边缘含金石英脉型、浅变质含碳碎屑岩型，并具多期次矿化特征；同时，金矿床（点）受控于逆冲推覆前缘叠瓦断层带。
Gold mineralization occurrences including several gold deposits in Beishan area belong to mesothermal epithermal deposits. Based on the metallogenetic characteristics, four mineralization types can be divided in Precambrian para greenschists, in fragmented altered rocks, in Au bearing quartz veins of basic intrusion edges, and in low metamorphic carbonaceous clasolites. The metallogenetic characteristics show that the gold deposits formed during polystages of mineralization and were controlled by the front imbricated fault zones of the NEE SWW large thrust nappe.
