赣南地区钨矿找矿史回顾及新一轮钨矿找矿思考

江西南部是驰名中外的黑钨矿富集区,不但黑钨矿储量之丰、品位之富、矿床之密集享誉世界,而且钨矿找矿理论与方法也为世界一流水平。本文首先简要回顾赣南钨矿勘查历史,概括第一轮钨矿找矿三大重要理论成果:一是标志带深部找矿;二是“数大脉”的就矿找矿;三是“探边摸底”发现岩体型钨矿;其次近年来在继承和发展上述理论成果基础上,取得的新增资源量与新发现矿产地,以及矿化新类型等重大进展。藉此,反映以往理论成果在新一轮钨矿找矿中的作用,证明赣南新一轮找钨矿的巨大潜力,并提出今后钨矿找矿方向和找矿方法,即三大主要思路:一是集中在“五大”钨矿找矿远景区,借助有利的找矿线索,运用“五层楼” “地下室”模式向老矿区外围、深部拓展找矿空间;二是不断开拓思路、扩大视野,通过“破碎蚀变岩型”等新类型钨矿找矿的突破,开辟新的找矿远景区或靶区;三是经过进一步探索,争取形成一套适用于该区钨矿找矿的快速评价方法,包括地球化学模型、模式类比等。

The historical review of ore-searching and the new thinking of tungsten ore prospecting in south Jiangxi

It is known at home and abroad of the black tungsten ore concentrated area of south of Jiangxi,not only for its rich in abundance,but also for its ore prospecting theory and the method at first level in the world.This article first briefly reviewed the south of Jiangxi tungsten ore investigation history,summarized three big important achievements during the first turn of tungsten ore prospecting period:"counting large veins" for ore prospecting;the guide belt in depth portion for ore prospecting;"prospected the edge and its depth of ore deposit to find out tungsten ".Based on the development of above theory achievements new deposits have been discovered,which shows the tungsten ore has huge potential in south Jiangxi.The further ore-searching direction and method are provided.First,looking for tungsten in the five large tungsten areas,with the aid of the advantageous prospecting clue,using five layer plus the basement pattern to find the ore outside the old mining area periphery and layer ore in the deep portion.Based on the breaking through the crashed-eroded rock type,new ore prospecting target area will be found out;According to the studying the geological features the process further exploration,a appraisal method,including ore deposit discovery(geochemistry model) ore deposit exploration persimmon pattern analogy) for search tungsten will be established.
