综合电法勘探在辛家咀金矿含碳质岩系中的应用研究
Application of Integrated Electrical Prospecting in Carbonaceous Rock Series of Xinjiazui Gold Deposit
摘要
Abstract
The Xinjiazui gold deposit in Qin-ling area is located in the west of Mianluoning Golden Triangle in Hanzhong,Shaanxi Province,This gold deposit has great metallogenic potential.However,Carbon-bearing stra-ta are widely distributed in the area,the traditional geophysical and geochemical exploration methods are inter-fered to some extent.In this paper,through the application of integrated electrical exploration such as audio magneto-telluric sounding(AMT)and induced polarization(IP)method,the deep morphological characteristics of ore-controlling fault in Xinjiazu gold deposit are identified,the combination of deep prospecting prediction technology and method for gold deposits in carbon-bearing strata is explored,the metallogenic mechanism is discussed and the ore deposit markers are summarized.Comprehensive electrical exploration can obtain the deep electrical structure characteristics of the study area,so as to locate and predict the deep occurrence location of gold deposits under the interference of carboniferous rock series and form the ore deposit markers.New discov-eries of regional prospecting have been obtained through the deep engineering verification,and the metallogenic mechanism of the study area is proposed.关键词
