摘要
廖家坪金锑矿床位于雪峰弧形构造中段,矿床空间定位和矿体展布受桃江—洞口脆-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的活化迁移,在适当的部位沉淀成矿;印支晚期叠加的脆性变形使金锑矿更一步富集。总结了该类矿床的找矿标志,认为该区金锑矿找矿应依托脆-韧性剪切带来开展。
The Liaojiaping gold-antimony deposit is located in the middle part of Xuefeng arc structural belt and controlled by the Tiaojiang-Dongkou brittle-ductile shear zone and the rocks in the deposit show distinct feature of shear deformation.The Indosinian ductile.shearing not only provided passway and space for mineralization,but also it makes metallogenic materials moving and precipitating in suitable place.The Indosinian brittle shearing resulted in further enrichment of gold-antimony.then summarizes the marks of ore exploration of this type.Believing that gold-antimony are exploration must be based on the brittle-ductile shear zone and pointing out the further orientation of exploration.
