【Abstract】 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.更多还原
