摘　　要：个旧锡矿层间氧化矿床品位高、工业利用价值大,加强这类矿床地质特征的研究,对于矿山深部及外围的锡矿找矿具有重要的指导意义。通过对个旧锡矿层间氧化矿床产出的地质特征、控矿因素的分析与研究,探讨了其矿床成因,并总结出:"背-突式"、"向-断-凹式"、"断-互式"及"断裂式"四种成矿模式。按这些模式的找矿实践表明,找矿效果极佳。The interlayer oxidized ore deposit in Gejiu tin mine is a high grade deposit of great value for industry use. There is a great guiding significance of geological feature research of this type deposit to the tin prospecting in the depth within the mine and its surrounding areas. Based on the research and analysis on the geological characteristics and ore controlling factors of interlayer oxidized ore deposit, four metallogenic models, named Hunch Back, Concave, Mutually Fractured and Fracture shape, are summarized. The ore genesis is discussed. The prospecting practice achieces a good effect according to these models.
