摘　　要：东安金矿床是黑龙江省境内新近发现的一个具有大型远景的金矿床。矿床受库尔滨壳断裂的次级断裂所控制 ,产于印支晚期碱长花岗岩和早白垩世中酸性火山 -侵入杂岩的强硅化蚀变带中。矿床成因类型属浅成中Dongan gold deposit in Xunke country,Heilongjiang province, as a large scale potential gold deposit was discovered recently,countrolled by the junior fractures of Kuerbin crust structure,and occur the silicon alteration zone of the intermediate acidity volcanic intrusion rock in early cretaceous and the late Indo Chinese epoch alkali feldspar granite.It is originally mid low temperature an epithermal type gold deposit.
