摘要
分析了陕甘川邻接区滑脱挤出构造与金矿床的空间关系、时间关系及其对地球化学元素活化迁移作用 .认为陕甘川邻接区的大型、特大型金矿主要受第二和第一次级滑脱带控制 ,为该区金矿远景区的预测提供了构造依据 .
The authors analyzed the space and time relationship between the décollement-extrusion tectonics and the gold mineralization in the adjoining area of Sichuan, Gansu and Shaanxi provinces and its effect on the activity and migration of geochemical elements in the décollement shear zone. The large and super-large gold deposits are all controlled mainly by the secondary- and primary-order décollement zones in the area. This reseach result provides us with the structural basis for the forecasting of gold-mine prospective location in this area.
