| 摘 要： | 根据长期的工作和研究成果,本文归纳总结了赣西卡林型金矿的成矿特征和找矿标志.赣西卡林型金矿产于扬子板块东南缘萍乡-高安坳陷带内,赋矿围岩为二叠系下统茅口组和三叠系下统大冶组等层位的细碎屑岩和不纯碳酸盐岩,金矿体产于断裂破碎带、层间破碎带、不整合面、密集裂隙带等构造部位,呈似层状、透镜状产出.金成矿受地层岩性、构造等因素的控制,在金矿床上均有化探金异常.找矿标志:1/5万化探分散流Au、AS、Sb、Hg组合异常;地层标志为大冶组和长兴组地层的细屑岩和不纯碳酸盐岩;构造上应在不整合面、断裂破碎带、密集裂隙带中.重点找矿远景区是坳陷带内两大推(滑)覆构造对冲带南侧的化探金异常区.
