| 摘 要： | 东安金矿是黑龙江省发现的大型浅成低温热液低硫化物型金矿床。赋存于中生代潜流纹岩和晚印支期碱长花岗岩接触外带的断裂系统中，近矿围岩硅化强烈、冰长石化发育。通过对潜火山岩的控矿作用研究，认为该区钙碱性中酸性潜火山岩是成矿的重要条件。

| Abstract: | The Dongan gold deposit is a great epithermal deposit newly discovered in Heilongjiang province.The deposit is distributed in contact zone and outer contact zone of subvolcanic rhyolite of Mesozoic and late Indosinian alkali feldspar granite. The alterations of wallrock are mainly strong silicification and orthoclase.According to the study on ore-controlling role of subvolcanic rock,the authors think the calcium-alkali and intermediate acid subvolcanic rocks are important conditions for mineralization. |
