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。
The Xicheng lead-zinc ore field is located in the West Qinling orogenic belt. The Pb-Zn ore deposit in this area is dotted with points and the ore-bearing construction is characterized by the shallow marine facies-marina clastic-carbonate sediments. The formation and distribution of the deposits are obviously controlled by the horizon , Deposit types can be divided into sedimentary metamorphic rock type and sedimentary metamorphism. Taking the Changba-Lijiagou lead-zinc deposit as an example, this paper discusses the characteristics of typical ore structure, analyzes the influence of regional metamorphism on the structure and structure of rock ore, and compares the ore structure and tectonic difference of different ore deposit types. And prospecting exploration has reference value.
