【摘要】 文章结合微细粒金矿床的矿物组成及岩、矿石的电性参数分析了高龙金矿利用电法勘探圈定成矿靶区的可行性。根据已知矿体上的视电阻率、视极化率特征,总结出高龙金矿不同类型矿床的激发极化和电阻率异常的规律。利用这些规律推断的异常基本得到证实。电法勘探的效果表明,在微细粒矿区采用物探方法圈定找矿靶区可以得到较好的地质效果。更多还原

【Abstract】 The feasibility of delineating metellogenic targets by using electrical methods has been analyzed based on the understanding of mineralogical composition of Carlin - type gold deposit and the petrophysical contrast between ore body and host rock in the Caolong Gold Mine. Resistivity and induced polarization surveys have been carried out for the exploration of the gold deposits in the area. Four IP anomalies with different resistivity features (?) have been obtained. Among them, two are well correlated with known deposits; one has been verified with geological data to be caused by gold ore body; while another one is due to the carboniferous strata. The results indicate that electrical methods may be successfully applied in the exploration of Carlin - type gold deposits.更多还原
