黑龙江省萝北-嘉荫成矿带是我国比较重要的金成矿带,该成矿带上分布有团结沟特大型斑岩型金矿以及杜家河等中、小型金矿床和矿化点,其中绝大部分严格受控于近SN向的乌拉嘎-嘉荫河深断裂带。斑岩型金矿矿体主要产于不同方向断裂的交汇区,而破碎带蚀变岩石英脉型金矿矿体则平行于主断裂呈雁行状排列或密集平行斜列。对矿床产出地质背景的分析认为,区域内的花岗岩体、花岗斑岩体、斜长花岗斑岩体为寻找斑岩型金矿的首选靶区;而横道河子和杜家河上游为寻找破碎带蚀变岩石英脉型金矿的有利区域。
The Luobei-Jiayin metallogenic belt in Heilongjiang Province is a relatively important gold metallogenic belt in China. There are large-sized gold-bearing porphyry gold deposits of Tuanjiegou and medium- and small-sized gold deposits and mineralization sites such as Dujiahe, Most of them are strictly controlled by the Wulaga-Jiayinhe deep fault zone near the SN. The porphyry-type gold ore body is mainly produced in the intersection of different direction faults, whereas the fractured zone altered rock-type vein gold type ore body is arranged parallel to the main fault in the geese or dense parallel oblique columns. According to the analysis of the geological background of the ore deposit, the granite body, granite porphyry body and plagiogranite porphyry body in the area are the preferred target areas for finding the porphyry type gold deposit; while the Hengdaohezi and the upper reaches of Dujiahe In order to find the favorable area of the crustal altered rock type vein type gold deposit.
