| 摘 要： | 西成铅锌矿田位于西秦岭造山带内，该区铅锌矿床点星罗棋布，含矿建造为浅海相--滨海相碎屑岩--碳酸盐岩沉积建造，矿床的生成和分布明显受层位控制，矿床类型可分为沉积变质岩型和沉积变质再造型。本文以厂坝--李家沟铅锌矿床为例，探讨典型矿石组构特征，分析区域变质对岩矿石结构、构造的影响，对比不同矿床类型矿石结构、构造差异，对本区矿产地质及成因研究和勘查找矿具有参考意义。

| Abstract: | Xihe-Chengxian lead-zinc ore field is located within west Qinling orogenic belt,where numerous deposits and mineral occurrences are scattered.Ore bearing formation is a sedimentary formation of neritic-litoral faces clastic rock and carbonate rock.The formation and distribution of deposits are obviously controlled by stratohorizon,and the type of deposits can be grouped into 2 types,sedimentary metamorphic type and sedimentary metamorphic recomposed type.In this paper,Changba-Lijiagou lead-zinc deposit has ... |
