| Abstract: | The Niuquan Silver-gold deposit locats in north margin of North China geodepression The ore formation conditions are obviously controlled by the fault structures and volcanic apparatus, both of them were originated from the activities of geodepression and the movement of continental extension in the late Yanshanian period The occurrence of ore deposit is chimney-like, and is composed of crypto-explosive breccia, and the genesis is of epi-hydrothermal type |
