| 摘 要： | 黑龙江省多宝山地区发育多期以铜金为主的成矿作用。加里东中期形成了斑岩型铜钼(金)矿床,燕山早期主要形成了矽卡岩型铜铁(金)矿床,燕山晚期形成了浅成热液型金矿床。不同时期矿床的空间分布受古生代海相火山岩为主的地层的控制,同时,受到NE向和NW向2组断裂交叉形成的环(菱)形构造的控制。各期岩浆作用最晚阶段形成的硅铝质含量较高且成矿元素明显富集的小型侵入体与成矿关系最为密切。多宝山地区是不同时代构造-岩浆作用的中心地带,富含铜、金等成矿组分的中奥陶统多宝山组海相火山岩地层是不同时代矿床的统一矿质来源,导致不同时代的成矿作用叠加发生、不同时代矿产种类具有一致性以及矿床集中分布等特点。

| Abstract: | There are multi-periodic Cu-Au ore-forming processes in Duobaoshan area, Heilongjiang Province, which involve Middle Caledonian, Early Yanshanian, and Late Yanshanian periods. The mineralization and metallogenic regularity of ore deposits formed in these periods are discussed in this paper. The porphyry Cu-Mo-(Au) deposits were mainly generated in Middle Caledonian period, the skarn Cu-Fe-(Au) deposits and Mo-W-Zn deposits were mainly formed in Early Yanshanian period, and the epithermal gold mineralization took place in Late Yanshanian period. These different types of ore deposits are mainly controlled by the Middle Ordovician and Lower Devonian strata and the ring structure associated with the NE- and NW-trending faults. The small plutons formed during the late stage of the magmatic evolution are often associated with these ore-forming processes. |
