摘　　要：基于近年在架底金矿及外围的找矿实践,在梁山组中发现了构造蚀变带。岩石孔隙度、渗透率研究表明,梁山组各层位成矿可能性由高到低分别为砂岩—泥岩,灰岩不利于成矿;构造地球化学分析表明,梁山组构造蚀变带中Au、As、Sb、Hg四个元素具有相同的含量变化趋势,为明显的正相关,以As元素最为明显,与黔西南地区卡林型金矿的强相关元素组合一致,是热液蚀变的结果。梁山组蚀变带既是寻找架底地区卡林型金矿的重要找矿标志,又是重要的容矿空间。Based on recent mineral exploration practices in theJiadi gold deposit and its surrounding areas,a structural alteration zone was identified in the Liangshan Formation.Studies on rock porosity and permeability indicate that the mineralization potential of strata in the Liangshan Formation decreases from sandstone to mudstone,and limestone is not conducive to mineralization.Structural geochemical analyses show that the variation characteristics of Au,As,Sb,and Hg content in the structural alteration zone of the Liangshan Formation are similar,with clear positive correlations,especially for As.These strongly correlated element combinations are consistent with the Carlin type gold deposits in southwestern Guizhou,and are the result of hydrothermal alteration.The Liangshan Formation alteration zone is not only an important prospecting indicator but also an important ore bearing space for Carlin type gold deposits in the Jiadi area.
