西藏左贡县拉荣钼钨矿区出露钼钨矿(化)体3处,分别产于二长花岗斑岩和北西、北北西向破碎带中,赋矿岩石为矽卡岩、二长花岗斑岩、碎裂岩、变质砂岩、石英板岩、板岩;矿种以钨为主,钼次之.本文分析了矿床成因属与浅成侵入岩有关的高温热液型钼钨矿床,成矿模式为矽卡岩型-斑岩型-碎裂岩型-变砂岩型;并估算了钼钨矿资源量(大型规模),为扩大找矿远景和矿床开发利用提供了有益借鉴.
The Larong molybdenum-tungsten ore district in Zuogang County,Xizang,is home to three molybdenum-tungsten ore bodies,which occur in the monzogranite porphyry and the NW and NNW fracture zones,respectively,and the host rocks are skarn,monzogranite porphyry,cataclasite,metamorphic sandstone,quartz slate and slate.It is pointed out that the genesis of the deposit is a high-temperature hydrothermal molybdenum-tungsten deposit related to epithermal intrusive rocks.The metallogenic model is skarn-porphyry-cataclasite-meta-sandstone type.The molybdenum and tungsten resources have been estimated to be large.
