摘　　要：黑龙江省大兴安岭地区多金属矿床主要赋存在地质层中,研究黑龙江省大兴安岭地区多金属矿床地质成矿背景及找矿方向,可以为大兴安岭地区多金属矿床的找矿提供理论依据。本文分析大兴安岭地区多金属矿床的地质岩层特性,通过对该地区开展矿产预查工作,分析大兴安岭地区多金属矿床中的灰紫色长石岩屑砂岩、岩屑石英细砂岩以及金、银、铜多金属矿床分布,结合区域内地层和岩浆岩,构造多金属矿床的成矿体系结构模型,在不同的成矿物理化学条件下实现找矿优化。The polymetallic deposits in the Daxinganling Area of Heilongjiang Province are mainly hosted in geological layers,studying the geological metallogenic background and prospecting direction of polymetallic deposits in the Daxing’anling area of Heilongjiang Province can provide a theoretical basis for the prospecting of polymetallic deposits in the Daxinganling Area.This paper analyzes the geological and rock formation characteristics of the polymetallic deposits in the Daxinganling Area,and analyzes the gray-purple feldspar lithic sandstone and lithic quartz fine sandstone in the polymetallic ore deposits and the distribution of gold,silver and copper polymetallic deposits in the Daxinganling Area by carrying out mineral prospecting work in the area,and constructs the metallogenic system structure model of polymetallic deposits based on the strata and magmatic rocks in the region,and realizes the optimization of ore prospecting under different metallogenic physical and chemical conditions.
