Abstract

Yongping copper deposit is located at the collisional belt between Yangtze Block and Cathaysia Block. It is a historic mine, and plays an important role in China’s copper production. Owing to the complicated geologic settings, the genesis of this deposit remains controversial for decades; VMS and generalized Skarn have been proposed. According to the VMS model (Gu et al., 2007), Yongping deposit formed in late Paleozoic basins, appearing as strata-bound massive sulfides, and underwent remobilization of ore and magmatic hydrothermal overprinting by Mesozoic magmatism. Nevertheless, Mao et al. (2011) proposed a tectono-genetic model for porphyry-skarn-stratabound Cu-Au-Mo-Fe which is really suitable for Yongping Deposit. However, all these studies focus on regional scale rather than local scale. Therefore, we try to concentrate on small scale, ore textures for instance, to search for evidence of the genesis of this deposit.
