摘要: 以豫南大别山北麓地区汤家坪大型斑岩型钼多金属矿床为例,阐明了豫南大别山北麓地区斑岩型钼多金属矿床的成因以及其地质与地球物理特征。通过在汤家坪钼多金属矿区开展综合物探找矿(可控源音频大地电磁测深法和频谱激电法)、剖面性试验研究和对区内所出露的岩(矿)石标本进行物性测试,试验及测试结果表明,该地区斑岩型钼矿床具有高阻高极化的物性特征,可控源音频大地电磁测深法和频谱激电法对成矿地质体(花岗斑岩体)有较为明显的显示。经钻孔验证表明,可控源音频大地电磁测深法和频谱激电法在该地区寻找斑岩型钼矿床是行之有效的,为今后在该区域寻找斑岩型矿床提供了技术参考,也为下一步推进该区地质找矿工作统筹部署和快速突破提供技术保障。

Abstract: Taking the Tangjiaping large-scale porphyry molybdenum multi-metal deposit in northern piedmont of Dabieshan in south of Henan province as an example,the cause of porphyry molybdenum polymetallic deposit in the northern piedmont of Dabieshan in south of Henan province and its geological and geophysical characteristics are elaborated.The comprehensive geophysical prospecting method is carried out in the typical mining area(controlled source audio frequency magnetotelluric sounding method and induced polarization method),profile test and the test of the physical property of the exposed rocks in the mining area are made.The experimental results show that the porphyry molybdenum deposit in the area has the features of high resistivity and high polarization,and the displays of metallogenic geological body and porphyry body are obtained by adopting the controlled source audio frequency magnetotelluric sounding method and the induced polarization method.The drilling results show that,the controlled source audio frequency magnetotelluric sounding method and induced polarization method are competent to search for porphyry type molybdenum deposit in the area.Therefore,the research provides technical reference for further exploration of porphyry deposit in the area and also provides technical support for deployment and rapid breakthrough in further geological prospecting work.
