Ore-controlling structures of micro-disseminated gold deposits in Pingle depression, central-western Jiangxi

The ore-controlling structures of micro-disseminated gold deposits in Pingle depression are composed of high-angle fault of Wugong extensional fault system, subhorizontal bedding detachment fault and brachyanticline derived in the stretching process, constituting a structural network which becomes a good channel-way for gold-bearing hydrothermal circulation. The distribution of gold orefields is controlled by low-level brittle deformation range of the extensional fault system, the distribution of gold ore belts is controlled by the root and peak of the low-level brittle extensional fault, the distribution of gold ore districts is controlled by the brachyanticline derived in the stretching process, and the distribution of gold deposits is controlled by the subhorizontal dotachment fault and anticline axis of brachyanticline.
