中文摘要：

航空瞬变电磁法在国外多金属矿产勘查中应用效果显著,尤其是在块状硫化物矿勘查中。该类型矿产在国内分布较为广泛,主要勘查手段为地面物化探方法,但周期长,受地形影响大。为此,国内引进航空瞬变电磁法,并首次在黄土坡矿床开展测量试验,结果表明矿床上方具有航电异常显示,低阻体空间上与主矿体吻合较好,并在主矿体南侧新发现一处航电异常,为该矿床深边部找矿提供线索。本文开展的航空瞬变电磁法测量试验找矿效果分析,为国内多金属矿产勘查,尤其是块状硫化物矿的找矿工作提供了方法技术借鉴。

英文摘要：

Airborne transient electromagnetic,as the advanced geophysical prospecting technology,has significant effect application in polymetallic mineral exploration in oversea countries,especially in the exploration of massive sulfide ore.This type of mineral deposits was widely distribution in China.The ground geophysical methods are the main exploration ones,but they have many problems such as long time cycle period,landform affecting,etc.In that case,the airborne transient electromagnetic method was introduced and carried out measurement test in Huangtupo deposit.The results show that there are several EM anomalies in the deposit and the low resistance bodies are coincided with the main ore body.Also,a newly anomaly was discovered in the south of main ore which providing clues for the depth of ore prospecting.The success of this test provided a reference technology for many domestic metal mineral explorations,especially for the massive sulfide ore prospecting work.
