陕西镇安金盆钨矿床地质地球化学特征与矿床成因

摘要

金盆钨矿床位于大西沟-黄金美钨(钼)矿化带内,通过矿床地质特征研究指出该矿床成因类型为矽卡岩-石英脉型钨矿床.根据成矿地质条件,结合典型钨矿床特征及区域对比研究,初步建立了金盆一带矽卡岩型-石英脉型钨矿的成矿模式.依据金盆钨矿床的地质、地球化学异常特征,明确了金盆钨矿床的找矿地质条件、信息准则与标志,对于金盆矿床深部及边部、以及江口-太白庙一带的矽卡岩型、石英脉型钨(钼)多金属矿的找矿工作具有重要的借鉴意义.%Jinpen tungsten deposit is located in the Daxigou-Huangjinmei tungsten-molybdenum mineralized belt.By means of researching on geological characteristics of the deposit,it has indicated that the deposit belongs to that type of skarn-quartz veins tungsten deposits.Based on the metallogenic geological conditions,combined with characteristics of typical tungsten deposits and regional comparison, it has initiatively established the metallogenic model of skarn-quartz veins type of tungsten deposits in the Jinpen area.According to the characteristics of geolog-ical and geochemical anomaly, the exploration geological conditions, information and principles, identifications have been defined,which is much significant for guiding the W-Mo polymetallic ore bodied both in the deep and marginal sites of Jinpen tungsten deposit,and in the belt of Jiangkou-Taibaimiao.
