秦皇岛市矿床的成矿地质条件及地质构造演化研究

Study on metallogenic geological conditions and geological structure evolution of Qinhuangdao deposit

秦皇岛市矿床成矿主要受到地层、区域构造以及岩浆岩三个地质条件影响,不同时代地层对一些矿产具有明显的控制作用,为矿床形成提供物质来源,地质构造方面主要受盆-山两类构造背景控制,为后期热液成矿作用提供物源,岩浆岩主要为中生代火山-侵入岩,为矿床的形成提供了良好的传输介质;通过对矿床地层、岩浆岩以及构造控矿的演化规律分析得出,秦皇岛市矿床山深部以及外围具有一定的找矿潜力。

The mineralization of Qinhuangdao deposits is mainly affected by three geological conditions:strata,regional structure and magmatic rocks.Strata of different ages have obvious control on some minerals,providing material sources for the formation of deposits.Geological structure is mainly controlled by basin mountain tectonic background,which provides material source for later hydrothermal mineralization.Magmatic rocks are mainly Mesozoic volcanic intrusion Through the analysis of the evolution law of strata,magmatic rocks and structural ore control,it is concluded that there is a certain prospecting potential in the depth and periphery of the deposit mountain in Qinhuangdao city.
