本文从地质-热力学-实验-地质的角度出发,研究了小寺沟钼铜矿床成矿作用过程中的地球化学演化特征,探讨了矽卡岩矿体与斑岩矿体之间的关系,提出了矿床的形成机理及模式。 1.矿床的地质地球化学特征 矿床的大地构造位置处于华北地台的边缘、内蒙地轴与燕辽沉降带过渡带的东南端。区内构造以断裂为主,计有近东西向、北北东
Based on the geology-thermodynamics-experiment-geology, this paper studies the geochemical evolution of the Xiaosigou molybdenum-copper deposit in the process of mineralization and discusses the relationship between skarn ore bodies and porphyry ore bodies. The formation mechanism and mode of the deposit. Geological and geochemical characteristics of the deposit The geotectonic location of the deposit is located at the edge of the North China platform and the southeast end of the transitional zone between the Inner Mongolia axis and the Yanliao settlement belt. The area is dominated by faults, with near east-west and north-north east
