新疆托克逊县某钨矿床地质特征及成因分析

Analysis of Geological Characteristics and Genesis of A Tungsten Deposit in Toksun County,Xinjiang Province

新疆托克逊县某钨矿床位于塔里木板块与准噶尔板块缝合带南侧,处于萨阿尔明—库米什晚古生代沟弧带内。在研究区域成矿条件和该矿床地质特征的基础上,分析该矿床成因。结果表明,该矿床主要为接触交代矽卡岩型钨矿床,是岩浆期后热液在接触带进行交代充填成矿作用的产物。

A tungsten deposit in Toksun county is located at south of suture zone between Tarim plate and Junggar plate, in Saaerming-Kumux Late Paleozoic trench-arc zone. The paper analyzes the genesis of the deposit based on the study of the regional metallogenic conditions and geological characteristics of the deposit. The results show that the main cause of deposit is skarn-type tungsten deposit. The deposit is the product of a magmatic hydrothermal filling in the contact zone.
