摘要
独具特色的秦岭复合型大陆造山带位于中国南北大陆中央 ,由古生代盆 -岛兼杂的小型陆块及其南北缝合构造带组成 ,并与华北和扬子大陆碰撞镶嵌。中—新生代陆内造山形成山盆耦合 ,构成独特的地质构造格局 ,造就了闻名于世的秦岭成矿带。形成贵金属、有色与黑色金属为特色的丰富矿产资源。根据秦岭造山带的组成与结构 ,阐述本区造山 -成矿作用机制下在不同构造单元中形成的复杂的金矿床类型。分析了秦岭造山带金矿类型产出的地质背景、分布规律及成矿潜力。
The distinct Qinling compound continental orogenic belt is located in the center of NS continent, China. It is composed by NS stylolitic structural belt and Paleozoic small landmass including basin and island, and is collided and enclosed each other by North China and Yangzi continents. Meso Cenozoic orogenic movement in the continent caused coupling of mountain and basin, which formed the distinct geologic tectonic framework, famous Qinling metallogenic belt and the abundant mineral resources characterized by precious, nonferrous and ferrous metal. Based on the component and structure of Qinling orogenic belt, the complex types of gold deposits formed in the different structural units were illustrated in the mechanism of orogenesis mineralization. The gelogic setting, distribution and mineralized potential of the types of gold deposits in Qinling orogenic belt are analysized.
