黑龙江省东部大型岩金矿床成矿条件分析及找矿方向探讨

The metallogenetic condition and prospecting direction of large primary Au deposit of the eastern part of Heilongjiang Province

本文对黑龙江省大型岩金矿床的构造地质环境、成矿地质条件进行综合分析,总结出大型岩金矿床的形成要有:①多种成矿物质来源;②多样式成矿方式;③多期次成矿活动叠加。并以“三多”为找矿方向,优选出4处大型岩金矿床的找矿靶区。

The tectonic setting and metallogenetic condition of large primary Au deposit of the eastern part of Heilongjiang Province are synthetically analyzed.It is summed up that the formation of large primary Au deposit has three soures,namely,multiple source metallogenetic materials;multiple metallogenetic types;multiperiodic activities superimposition.According to these three characteristics,it is determined that there are 4 prospecting target areas of large primary Au deposits.
