摘　　要：老万场式金矿是黔西南金矿成矿区内的一种新类型金矿，成因类型属岩溶塌陷异地堆积红土型，是背斜或穹隆核部原有卡林型金矿因下伏碳酸盐系高度岩溶化发生塌陷坠入岩溶洼地后经红土化而成矿的，原有卡林型金矿是其物源，岩溶洼地为其储存和成矿场所。二者在成因上相互联系，空间上互为消长，笔者强调：在区域成矿总体有利的前提下，凡是卡林型金矿的赋矿层位已被剥蚀，下伏碳酸盐系已大片暴露的背斜和穹隆核部，应注意寻找该类型金矿。有利的赋矿空间为“宽谷”地文期（晚第三纪末—第四纪初）的岩溶洼地，特别是沿高角度断层发育的洼地。A type of gold ore deposit, whose ore forming materials derived from Carlin-type gold ore deposit and which can be called allochthonous accumulated latentic gold deposit due to karst subsidence, is found. There is a close relationship between it and Carlin-type deposit, i. e.both of them exist in the same metallogenetic province but repel one another in space at a deposit size. It is emphasized where the Carlin-type gold deposits are denuded and the underlying carbonate is exposed this kind of deposit should be searched for.
