| Geological Characteristics and Structural Ore-controlling Role of the Dongping Gold Deposit, Hebei Province |
| Orebodies of en echelon distribution, superimposed mineralization of quartz vein type as well as tellurium-rich and sulfur-poor type ore make up three characteristics of the Dongping gold deposit in Hebei Province. Orebodies of en echelon distribution seem to be the most prominent feature. The couple was produced in Yanshanian SN-trending stress pattern, and NNE-striking, NW-dipping left lateral en echelon compressional-shear fractures and NW-striking, SW-dipping right lateral en echelon tensional-shear fractures were formed in Dongping area. They traced each other in space,and NNE-striking fractures restricted the development of the NW-striking fractures. Two directive fractures composed Xi-type fractures system and controlled the mineralization of the gold deposit. |
