摘　　要：滇黔桂及周邻区为卡林型金矿集中产出区,是我国最重要的金矿资源产地之一。基于贵州西南部地区金矿研究和找矿实践,拓展了构造蚀变体(SBT)的内涵,建立了其判别指标,并简述了区域成矿与找矿空间之间的关系。研究表明,构造蚀变体是成矿作用的产物,产出于岩石能干性差异大的地层不整合面和岩性层界面之间。基于区域多层次产出的构造蚀变体,构建了滇黔桂地区卡林型金矿多层次构造滑脱成矿系统,为系统研究区域卡林型金矿成矿奠定了基础;建立构造蚀变体判别指标并准确识别,对开展滇黔桂及周邻区卡林型金矿成矿预测,指导找矿勘查具有重要意义。The Yunnan-Guizhou-Guangxi area and its surrounding area in China are the carlin-type gold deposit producing areas,which is one of the most important gold resources producing areas in China.Based on the study and prospecting practice of gold deposits in southwest Guizhou,the structural body alteration(SBT)is expanded,its discriminant index was established,and the relationship between regional mineralization and prospecting space was briefly described.The results show that structural body alteration is the product of mineralization and occurs between the unconformity surface and lithologic layer interface where the rock capacity varies greatly.Based on the structural body alteration of regional multi-level output,the multi-level structural detachment metallogenic system of carlin-type gold deposits in Yunnan-Guizhou-Guangxi area is constructed,which lays the foundation for the systematic study of regional carlin-type gold deposits.It is of great significance to establish the discriminant index and identify the structural body alteration accurately for the metallogenic prediction and prospecting of carlin-type gold deposits in Yunnan-Guizhou-Guangxi and its surrounding areas.
