江西万安弹前地区钨矿成矿特征

The Mineralization Characteristics of Tungsten in Tanqian Area of Wanan County In Jiangxi Province

江西万安弹前地区岩体经同期多次多阶段活动形成复式岩体,断裂、节理相对发育,岩浆期后经气化高温热液成矿流体介入,形成石英脉型钨矿,以块状和带状产出为主。区内黑钨矿主要产于弹前岩体内的小构造断裂带、裂隙带及节理中。本文主要分析区内成矿岩体、矿床成因及矿体特征,为下步区内寻找类似矿床提供找矿标志。

The tanqian rock mass in wanan county has been formed Compound rock mass experience multiple stage activities over the same period,Fracture and joint structure are developed,After the magmatic phase,the hydrothermal mineralization fluid was involved,A quartz vein type tungsten deposit is formed,Based on block and strip output.The black tungsten deposit in the area is mainly produced in the small structure fracture zone,fracture zone and joint in the rock mass.This paper mainly analyzes the mineralization rock mass,the genesis of ore deposit and the characteristics of ore body,Find the ore marker for the tungsten deposit in the next step area.
