尕大阪地区地电化学提取法找隐伏矿床的应用

Geoelectro-chemical extraction method for prospecting concealed deposit in Gadaban area

郭米寺—尕大阪铜多金属矿区位于北祁连成矿带走廊南山铜多金属成矿亚带,中寒武统黑刺沟群为主要的赋矿地层,北西西—南东东向高角度逆冲断裂是区内主要的控矿构造。本文利用地电化学法对郭米寺—尕大阪铜多金属矿区覆盖区进行找矿实验研究,实验结果在已知矿区的剖面上测出了清晰的地电化学异常,表明利用地电化学法在本区寻找隐伏矿是有效的。

Guomisi - Gadaban copper polymetallic deposit is located in the northern Qilian metallogenic belt corridor in the Nanshan copper polymetallic metallogenic subzone. Middle Cambrian Heicigou group is the main ore bearing strata, and North West-South East to high angle thrust is the main ore controlling structure. The location chemistry method was used to carry out prospecting experiment in Guomisi -Gadaban copper polymetallic mining area. Clear geoelectrochemical anomaly in known mining section indicates that the location chemistry method is effective in prospecting for concealed ore deposits in this area.
