磁法在青海茫崖河东地区铁多金属矿勘查中的应用

青海省祁漫塔格成矿远景区地质上处于东昆仑、阿尔金构造带和柴达木地块等几个重要构造单元交汇的构造结上,经历了复杂的地质构造演化过程。近年来,相继发现了白干湖大型钨锡矿床,以及具有大型远景的卡尔却卡铜多金属矿床等,找矿成果显著。青海省茫崖河东地区在青海省祁漫塔格成矿远景区内,区内构造、岩脉发育,找矿潜力大。本次研究利用高精度磁测物探方法,并结合研究区地质特征,很好地指导了该区找矿工作。

Application of magnetic method in prospecting for iron polymetallic ore in the Mangya River East area of Qinghai

The Qimantage prospecting area in Qinghai Province is geologically located on the tectonic knot where several important tectonic units such as the East Kunlun, the Altyn structural belt and the Qaidam block converge, and has undergone complicated geological structural evolution. In recent years, it is remarkable in prospecting because of the Baigan lake tungsten-tin deposit as well as the large-scale prospect of Karl Zuka copper polymetallic deposit and so on. The Mangya River east region is located in the ore-forming prospect area of Qimantage metallogenic zone in Qinghai Province, its unique structure and dyke development, which makes a good potential for prospecting. In this paper, the high accuracy magnetic measurement for geophysical prospecting, combined with the geological characteristics of the study area, which is a good guide for prospecting work in this area.
