| 摘 要： | 已知锡矿床(点)余处的湘南地区锡矿资源丰富,探明锡金属量×100n106。锡矿 t 的分布与燕山期花岗岩体密切相关;选矿效果较好的有云英岩—石英脉型、蚀变花岗岩型、蚀变断裂充填型锡矿,它们是当前开采的主要对象;锡矿找矿重点地带是郴州—蓝山构造岩浆岩带,近期的主要目标是到花岗岩中找蚀变花岗岩型和蚀变构造带型锡矿。

| 关 键 词： | 燕山期花岗岩 郴州－蓝山构造岩浆带 蚀变构造带 资源远景评价 找矿 锡矿床 |

| Abstract: | There are abundant Sn-ore resources (known Sn-deposit about 100 place, proved Sn- metal quantity several million tons.) Distribution of Sn-deposit closely correlates regional granite of YanshanPeriod. Well milling Sn-deposits of greisen-quartz vein, altered granite and altered fracture crown are mainly exploited at present. The important area for prospecting Sn-ore is structure architecture magmatite in Chenzhou-Lanshan. Present aim is prospecting Sn-deposit in granite of altered granite and altered fracture crown. |
