江西省大余县牛斋矿区地质特征及成因浅析

Geological Characteristics and Genesis Analysis of Niuzhai Mining Area in Dayu County,Jiangxi Province

牛斋钨矿区域上属南北向诸广山—万洋山构造岩浆岩带的东侧,南岭东西向复杂构造带与新华夏系万长山构造带复合部位;钨矿体由石英大脉型及矽卡岩型组成,矿石矿物主要为黑钨矿、白钨矿。是崇余犹钨锡矿化集中区外接触带矽卡岩型钨矿找矿的重要突破。笔者在野外勘查工作的基础上,归纳总结其成矿特征,本文论述了钨的赋存状态及其分布规律进行了研究,形成了牛斋钨矿找矿新进展新认识,为这对丰富赣南地区矽卡岩型钨矿研究及老区找矿具有借鉴意义。

Niuzhai tungsten deposit is located on the east side of the north-south Zhuguangshan Wanyangshan tectono magmatic rock belt,and the compound part of the east-west the Nanling Mountain complex structural belt and the Neocathaysian Wanchangshan structural belt;The tungsten ore body is composed of quartz vein type and skarn type,with the main ore minerals being wolframite and scheelite.It is an important breakthrough in the exploration of skarn type tungsten deposits in the outer contact zone of Chongyu You tungsten tin mineralization concentration area.On the basis of field exploration work,the author summarized and summarized its mineralization characteristics.This article discussed the occurrence state and distribution law of tungsten,and formed a new understanding of the new progress in the exploration of Niuzhai tungsten deposit.This has reference significance for enriching the research of skarn type tungsten deposits in the southern Jiangxi region and the exploration of old areas.
