河南省熊耳山地区已查明金、钼、铅锌各类矿床（点）数十个，显示出较好的成矿潜力。但矿床成矿物质来源的研究却非常薄弱，已有的研究也存在不同的认识，本文系统收集了熊耳山地区地层、岩浆岩及各类矿石的铅同位素组成，并计算了相关铅同位素参数，通过详细的铅同位素数据及相关参数对比，研究了矿集区内成矿物质来源。结果表明：熊耳山多金属矿集区成矿物质主要来自于岩浆岩。依据透岩浆流体成矿体系，岩浆源区物质是与富集成矿物质的流体经过充分岩石—流体相互作用的太华群古老基底物质，具有与地表出露太华古老基底变质核杂岩完全不同的铅同位素组成。
More than ten ore deposits including Au deposit, Mo deposits and Pb—Zn deposits have been discovered in the Xiong’er Mountain area, Henan Province, indicating good potential for mineral resources in this area. However, fewer attentions have been paid to constrain the sources of the ore forming metals for these deposits. And there are different viewpoints on this object between previous researchers. In this study, we review the published Pb isotopic compositions for the strata, igneous rocks, and various ores in the Xiong’er Mountain area, and use these Pb database to calculate some Pb isotopic parameters further. Based on detailed comparison of Pb isotopes and associated parameters for the strata, igneous rocks, and various ores in this area, we propose that ore forming metals of these deposits cloud be from igneous rocks. According to transmagmatic fluids ore forming system, the magmas were probably derived from the Neoarchean Taihua basement which was undergone strong rock—fluid interaction by the ore forming fluids. Thus, these magmatic rocks have distinguished Pb isotopic compositions with the metamorphic core complex of the Taihua Group that outcrops on the surface in this area.
