| Abstract: | Based on the field works,the paper summarized the minerogenetic geological setting, charac teristics of mineral deposits and prospecting methods, ect. of Xialong silver-gold deposit. It is confirmed that the ore bodies are controlled by the acid volcanic rocks of Xishantou Formation in Upper Jurassic. The natural types of the ore is altered tuff which contains pyrites bearing stock work and disseminated gold-silver ore. The genetic type of mineral deposits belongs to the vol canic hydrothermal alteration type. |
