摘　　要：龙王江锑砷金矿床由石英脉、破碎蚀变岩和蚀变糜棱岩矿体构成。矿体一部分呈平行分布,另一部分呈斜列分布,受劈理化带或剪切带控制。主矿体沿倾向延伸大,可构成垂深达千米的"超深矿柱"。锑砷金矿成矿是在Sb-As-Au特定的地球化学背景基础上发生的,构造应力是完成元素活化、运移和富集的地质地球化学过程的热(动)力。矿床成因属动力变质热液型。石英脉型和破碎蚀变岩型金(锑)矿具有较大的找矿潜力。通过综合分析提出了该矿床找矿标志与找矿方向。Longwangjiang Sb-As-Au deposit is composed of quartz vein,fractured alteration rock and mylonite ore bodies.Some ore bodies are parallel and others are en echelon.They are controlled by cleavage or shear zone.The main ore body extends long about1000m deep to form a super-deep pillar of ore.The deposit is formed under specific geochemical background.Structural stress resulted in geological and geochemical thermal dynamics which leads to element activation,transportation and enrichment.Genetically the deposit is a dynamically metamorphic hydrothermal deposit.In this area it is potential to prospect quartz vein and fractured alteration type ore.The the ore prospecting direction and marks are put forth through comprehensive.
