摘　　要：太古宙绿岩带是世界主要金矿赋存区,在古老的非洲地台分布很多绿岩带,其上叠加剪切带即伴随有含金建造的出现。本文根据安徽地矿"走出去"实施的某绿岩区金矿勘查资料、西霍嘎地块地质背景、区域上金矿赋存规律及邻区正在开采的金矿考察,初步分析了该区金矿地质特征、控矿要素、矿床成因及找矿标志,供后续勘查投资和周边中方相同地质背景矿权区找金参考。Archean greenstone belt hosts major gold ore deposits in the world.In the old African platform there are many greenstone belts,over which shear zones are usually associated with gold ore formations.Based on gold ore prospecting data on a greenstone area,geological setting of west Hoggar block,regional gold ore distribution law and investigation of gold ore mining in the vicinity of the study area,this paper preliminarily analysed geological features of the gold deposit,ore-control factors,deposit genesis and ore indicators.
