| 摘 要： | 位于雪峰弧形构造中段的江东湾金锑矿床，其空间定位和矿体展布受黔阳一溆浦韧性剪切带控制，矿区内岩石剪切变形特征明显。印支期韧性剪切变形不仅形成了导矿通道和容矿空间，更重要的是促使成矿物质活化迁移，并在适当的部位沉淀成矿；燕山期叠加的脆性变形使金锑矿进一步富集。总结了该类矿床的找矿标志，认为该区金锑矿找矿应依托韧性剪切带来开展。

| Abstract: | The Jiangdongwan gold-antimony deposit is located in the middle part of Xuefeng arc structural belt and controlled by the Qianyang-Xupu ductile shear zone. The Indosinian ductile shearing not only provided passway and space for mineralization,but also made migration and deposition of gold in suitable place. The Yanshanian ductile shearing resulted in further enrichment of gold and antimony. Besides,the authors summarize exploration marks of this kind of deposits and suggest that prospecting of gold-antimony deposits in the study area should be along the ductile shear zone. |
