赣南W、Sn多金属成矿区划及找矿方向

赣南地区是南岭成矿区(带)中重要的W、Sn多金属矿产聚集地,已探明黑钨矿储量和产量均居世界第一。区内主要矿化元素为W、Sn、Pb、Zn、Ag、Au、Nb、Ta、Mn等。主要矿化类型为石英脉型、破碎蚀变岩型钨矿,斑岩型、层间隐爆裂隙带型锡矿,隐爆角砾岩型铜矿,形成了与燕山期岩浆活动有关的钨锡多金属成矿系列。新矿化类型是赣南中生代岩浆—火山岩区找矿的重要方向。

Division of W and Sn multimetal mineralization region and its ore-searching direction in South Jiangxi

outh of Jiangxi is an important ore concentration area of tungsten and tin multimetal in the Nanling area.The reserves and output of black tungsten rank the first in the world.The main mineralization elements are W,Sn,Pb,Zn,Ag,Au,Nb,Ta,Mn etc in this area.The main types of mineralization are quartz-vein,crashed-eroded tungsten ore,porphyry type;layer cryptoexplosive fissures type tin mine and cryptoexplosive breccias copper mine.They formed the tungsten & tin metal mineralization series which are related with Yanshan magmatic period.This paper has pointed out the important direction for searching new mineralization type in Mesozoic Era magmatic-volcanic zone South Jiangxi.
