江西于都才逢寮钨矿地质特征及找矿前景

Geological Characteristics and Prospecting Prospect of Caifengliao Tungsten Deposits in Yudu,Jiangxi Province

江西于都县才逢寮钨矿位于合龙钨矿田北部,属外接触带石英脉型钨矿化,地表圈出六条标志带,钻探揭露钨矿脉数量多、脉幅较大、品位富,对照华南脉钨矿床"五层楼"模式,依据地质背景、地质及矿床特征,该区矿化露头尚属标志带,由浅入深探寻细脉带、薄脉带、大脉至巨脉带。其主要矿化带,从矿化标志带、矿脉的数量、规模和矿脉的厚度、矿石的品位及深部空间等分析,预测本区钨资源量可达中-大型规模。

The Caifengliao tungsten mine in Yudu County,Jiangxi Province is located in the north of Helong ore field,which belongs to quartz vein type tungsten mineralization in the external contact zone.Six marker zones are circled on the surface.Drilling reveals that there are many tungsten veins with large vein amplitude and rich grade.Compared with the"five storey"model of South China vein tungsten deposit,according to the geological background,geology and deposit characteristics,the mineralized outcrop in this area still belongs to the marker belt,and the fine vein belt,thin vein belt and large vein to giant vein belt are explored from shallow to deep.Explore the fine vein zone from shallow to deep Thin vein belt,large vein to giant vein belt.According to the main mineralized zones,it is predicted that the tungsten resources in this area can reach medium-large scale by analyzing the mineralization indicator zones,the number and scale of veins,the thickness of veins,the grade of ore and the deep space.
