河南省卢氏县小南沟金多金属矿床是熊耳山金、银、铜、铅多金属成矿带之北亚带中新发现的一个小型矿床。矿化以脉型为主,矿脉均受构造蚀变破碎带控制。本次工作选择有利位置进行了 EH 4电磁测深勘探,根据电磁测深结果布置了相应的钻孔验证,EH 4所圈定的异常带基本揭示了断裂破碎带的位置以及深部延伸情况,且与钻孔验证中位置对应较好,本方法在小南沟多金属矿区中与断裂破碎带密切相关的石英脉型金矿和铅矿的找矿工作是合理有效的,说明 EH 4电磁观测系统对于寻找与中大型断裂破碎带有关的石英脉型金矿床和铅矿有良好的勘探效果。
河南省盧氏縣小南溝金多金屬礦床是熊耳山金、銀、銅、鉛多金屬成礦帶之北亞帶中新髮現的一箇小型礦床。礦化以脈型為主,礦脈均受構造蝕變破碎帶控製。本次工作選擇有利位置進行瞭 EH 4電磁測深勘探,根據電磁測深結果佈置瞭相應的鑽孔驗證,EH 4所圈定的異常帶基本揭示瞭斷裂破碎帶的位置以及深部延伸情況,且與鑽孔驗證中位置對應較好,本方法在小南溝多金屬礦區中與斷裂破碎帶密切相關的石英脈型金礦和鉛礦的找礦工作是閤理有效的,說明 EH 4電磁觀測繫統對于尋找與中大型斷裂破碎帶有關的石英脈型金礦床和鉛礦有良好的勘探效果。

Xiaonangou Au polymetallic deposit in Lushi of Henan was a new discovered small scale deposit in the northern subzone of Xiong’ershan Au-Ag-Cu-Pb polymetallic metallogenic belt.The mineralization was typically in veined structure which was controlled by tectonic altered fracture zone.The author selected fa-vorable locations for EH 4 electromagnetic sounding and planned drilling works accordingly to verify the re-sults shown by electromagnetic sounding,and it is discovered that the anomaly belts blocked out by EH 4 ba-sically revealed locations and extensions in deep part of fracture zone which coincided well with locations veri-fied in drilling works.This method proved to be reasonable and effective in the prospecting of quartz-vein type Au ores and Pb ores which were closely related to fault fracture zone in Xiaonangou polymetallic mining area and the results indicated that EH 4 electromagnetic observation system was an effective prospecting method in searching for quartz-vein type Au ores and Pb ores which were closely related to medium-large-scale fault fracture zone.
