甘肃省庄浪县王家高原一带铜矿地质特征及找矿模型

Geological characteristics and prospecting model of copper deposits in Wangjia plateau,Zhuanglang County,Gansu Province

矿区位于祁连山北西向构造体系与贺兰-六盘山近南北向构造体系二者锐角交汇处,经历了自元古代以来不同时代、不同层次、不同性质的构造变形叠加改造,形成了复杂多样的构造样式和组合。两个深大断裂穿过本区,是区内的重要导矿、导热构造,为成矿物质迁移富集提供了重要的地质条件,热液来源与王家高原岩体的侵入作用有关。通过研究区域地质背景、地质特征、地球物理特征、成矿规律及控矿因素等建立了本区找矿模型。

The mining area is located at the intersection of Northwest structural system of Qilian Mountain and Helan Liupan Mountain near north-south structural system.It has undergone structural deformation superimposed transformation of different ages,levels and properties since Proterozoic,forming complex and diverse structural styles and combinations.The two deep faults,which pass through this area,are important ore guiding and heat conducting structures,providing important geological conditions for the migration and enrichment of ore-forming materials.The source of hydrothermal fluid is related to the intrusion of Wangjia plateau rock mass.Through the study of regional geological background,geological characteristics,geophysical characteristics,metallogenic law and ore controlling factors,a prospecting model is established.
