摘要
为了解决卡拉盖雷铜金矿寻找隐伏矿和深部矿体问题,采用大功率激电中梯装置和激电测深进行勘探,发现了2个高极化率异常,其中IP1为低阻高极化异常,IP2为中高阻高极化异常。经钻探结果验证,IP1发现了厚大的铜金矿体,IP2异常是由蚀变的片理化凝灰岩引起。大功率激电为矿区深部找矿提供了地球物理依据。
n order to solve the problem about how to search the buried and deep orebodies of the copper-gold mine of Kalagailei,application of the methods of High-power induced polarization and Induced polarization found 2 anomalies of high-polarization,one of which named IP1 was low-resistivity,and high-polarization and the other one named IP2 was medium-high resistivity and high-polarization. The drilling results showed that the IP1 was caused by the thick and large copper-gold ore-body,and IP2 by the altered foliated tufa. The study results demonstrated that the method of high-power induced polarization could provide geophysical evidences for deep mineral exploration in mine area.
