摘　　要：架底金矿是近年贵州西部发现的最大原生金矿床,以玄武岩为容矿岩石的微细浸染型金矿。赋矿部位为上层破碎蚀变带和下层构造蚀变体,均为区域构造作用和热液蚀变的综合产物。本文基于架底金矿床地质特征及金矿体在玄武岩区富集规律的总结,分析外围找矿方向,对该地区外围寻找玄武岩容矿金矿床具有实践指导意义。The Jiadi gold deposit is the newly discovered largestprimary gold deposit in western Guizhou.It is a micro-disseminated gold deposit hosted in basalt.The orebody is hosted in both the upper fractured alteration zone and the lower structural alteration rocks,which are the comprehensive products of regional tectonism and hydrothermal alteration.Based on the summary of the geological characteristics of the Jiadi gold deposit and the enrichment law of the gold ore body in basalt areas,the peripheral prospecting direction is analyzed in this paper,which provide practical guidance for the exploration of basalt-hosted gold deposits in the periphery areas of the region.
