| 摘 要： | 在分析大别山北麓区域成矿地质背景的基础上，对汤家坪大型斑岩型钼多金属矿床地质特征进行了系统描述，并开展了综合物探找矿研究，采用的方法主要包括岩（矿）石物性测试、可控源音频大地电磁测深法（CSAMT）和频谱激电法（SIP）。结果表明：斑岩型钼矿矿体与围岩之间存在物性差异，利用2种电法能够很好地反映成矿地质体的空间位置和形态，表明利用此类方法组合寻找斑岩型钼多金属矿床是行之有效的，为今后在该区域寻找斑岩型矿床提供了技术参考。

| Abstract: | On the basis of analyzing geological background of regional metallogenic in north of Dabie Mountains, geologic feature of large porphyry molybdenum polymetallic in the Tangjiaping was systemically described with the methods of stone of rock（ore）physical properties test,controlled source audio-frequency magnetotelluric sounding method（CSAMT）and spectrum IP method（SIP）.The results showed that there is phyical differences between porphyry molybdenum ore body and wall rock.Meanwhile,using the two kinds of electrical method can well reflect the ore-forming geological spatial location and morphology,indicating that the method combined with porphyry molybdenum polymetallic deposit was effective,which can provide important technical reference for porphyry deposits in the area in the future. |
