西藏多龙矿集区发现浅成低温热液型铜(金银)矿床
Discovery of the Epithermal Deposit of Cu (Au-Ag) in the Duolong Ore Concentrating Area, Tibet
摘要
Abstract
According to the latest survey results and detailed geological records in 2013, as well as some preliminary study about geological features and deposit type of south Tiegelong (Rongna) copper (gold-silver) deposit which located in Duolong copper (gold) ore concentration area, we believe that it is a porphyry related epithermal deposit. It is a typical high sulfidation epithermal deposit. Rongna is a huge Cu(Au-Ag) deposit. Here exist various attitudes of alunite and dickite, that is, typical banded, layered, crusty or massive ones and etc. Phyllic exists in the deep. The content of pyrite is 3%to 35%. Ore minerals consist of covellite, digenite, enargite, spionkopite, yarrowit, djurleite, anilite, bornite, tetrahedrite, chalcopyrite and other components. Comprehensive study has shown that there is an inferred high sulfidation epithermal deposit in the superficial or peripheral, and a porphyry copper (gold and silver) orebody in the deep. The discovery of south Tiegelong is brilliant which actually is an epithermal deposit. It has brought us a new chapter to find epithermal deposit in Tibet which is never an imaginable type here ever. This is quite significant for regional prospecting because it can give extremely meaningful implications for surveies.关键词
