摘要
东安金矿床是黑龙江省近几年来发现的浅成低温热液金矿床。矿床受隐角砾岩和断裂控制,赋存于中生代陆相火山—侵入岩及晚印支期碱长花岗岩强硅化带中。NNE向库尔滨壳断裂及其次级断裂为成矿的重要地质条件。
Dongan gold deposit is a new discovered hypabyssal hydrothermal deposit in Heilongjiang province. Controlled by fracture and fracture alteration belt, Dongan gold deposit is distributed in Mesozoic continental volcanic -intrusive rocks and late Indosinian periodical strong silication belt with alkali -feldspar granite. NNE Kuerbin crustal fault and its secondary fault anr the important conditions for ore forming.
