摘要
大坪钨矿为近年新发现的一处小型矿床,成矿定位于幕阜山花岗岩基四甲铺花岗岩北外缘,矿体产于北东向云英岩化花岗岩脉中,属云英岩型白钨矿床。研究总结了矿区成矿地质特征,探讨了矿床成因,从花岗岩标志、蚀变标志、地化标志来分析判断找矿方向,并明确了3处找矿有利地段。
The Daping tungsten deposit is a small deposit newly discovered in recent years.The metallogenesis is located at the north outer edge of the granite base of Sijiapu granite in Mufushan.The ore body is produced in the northeast-trending Yunying granitic vein and belongs to the Yunying type.Scheelite deposit.The study summarizes the metallogenic geological characteristics of the mining area,discusses the genesis of the deposit,analyzes and judges the prospecting direction from alteration signs and geochemical signs,and clarifies three favorable prospecting areas.
