自河北昌黎、经山海关至辽宁北镇的山海关地穹西北部边缘均有钼矿床分布。矿床形成于燕山运动的中—晚期,系含钼热液充填于岩石中的构造裂隙、矿物粒间孔隙而成。本区自燕山运动以来,在大地构造单元上,既不同于地台区,也不同于地槽区,而是转化为地洼区后,形成了地洼构造层。钼矿床与受青龙—锦西—阜新基底断层和女儿河断层控
The distribution of molybdenum deposits is from the Changli, Hebei, the Shanhaiguan Pass to the north of Shanhaiguan to the north of Liaoning Province. The deposit was formed in the mid-late Yanshanian movement. It is a tectonic fissure filled with molybdenum hydrothermal fluids in the rock and formed by intergranular pores. Since the Yanshan movement in this area, on the tectonic unit, it is not only different from the platform area but also from the terrain area, but transformed into the diwa area, forming the diwa structural layer. Molybdenum deposit and controlled by Qinglong - Jinxi - Fuxin basement and daughter river fault
