Geophysical Characteristics and Prospecting Direction of the Sinongduo Pb-Zn Deposit in Xietongmen County, Tibet
摘要
Abstract
The epithermal deposit is a kind of low-temperature hydrothermal deposits mainly hosted in continental volcanic rocks or related to continental volcanic rocks.The most important characteristic of this deposit is shallow burial depth,which makes geophysical methods have natural advantages in mineral exploration of epithermal deposits.Based on the study of geophysical characteristics of the Sinongduo polymetallic epithermal deposit,new Pb -Zn-Au-Ag epithermal hydrothermal orebodys are successfully discovered by using the integrated geophysical techniques such as the induced polarization.At present,there are 3 sections of ore bodies in the single project control,which are the top Au-Ag ore,the middle Au ore,and the bottom Pb-Zn-Ag ore.The highest grade of Au can reach 5.3 g / t and the Ag can be 410 g / t.The Pb + Zn grade is about 5.9 ％ on average.Research results show that the physical parameters of volcanic rocks of Linzizong group in the Sinongduo area are stable,and that the disturbance is relatively small.The Au epithermal deposits produced in the strongly silicified geologic masses of the Linzizong group volcanic rocks are mostly characterized by medium-high polarizability and medium-low resistance.关键词
