摘　　要：层间氧化矿是个旧矿区非常重要的一种矿床类型,受构造控制明显。本文在老厂矿田典型矿床构造控矿特征调查的基础上,系统总结层间氧化矿控矿规律。研究表明:老厂矿田层间氧化矿受含矿岩系层序构造、构造-岩体带状组合、层间-褶皱(挠曲)构造体系、层滑-断裂构造系统、断裂构造系统控制。Interlayer oxidized ore is a very important mineralization type in Gejiu mining area,which is obviously controlled by structure.In this paper,the ore-controllingregularities of interlayer oxidized ore were systematically summarized,based on the investigation of structural ore-controlling characteristics of typical deposits in Laochang orefield.The study shows that the interlayer oxidized ore in Laochang ore field is controlled by the sequence structure of ore-bearing rock series,a zonal combination of structure and rock mass,the interlayer-fold(flexure)tectonic system,the interlayer slip-fault tectonic system,and thefracture tectonic system.
