| Abstract: | On the basis of the regional geology, the geochemistry of deposit and the isotope chronology, this paper advances that the mineralization of Xujiapo gold-silver deposit is controlled by the Wudang group, the Wudang rise-slip structure and the Wudang thrust nappe structure,showing the stratum-structure control over mineralization and the polymineralization.The deposit has the complex metallogenic factors with the metallogenic materials originated from the deep. The genesis belongs to the gold-silver deposit of magmatic meso-epithermal solution with partial mixing of deep brine and metamorphic water. |
| Keywords: | Wudang rise-slip structure Wudang thrust nappe structure geochemical characteristic of deposit metallogeny Xujiapo gold-silver deposit |
