Ph.D. student XIAO Bo and his teacher QIN Kezhang research geological and mineralogical features of the Qulong deposit, as well as the result of fluid inclusion microthermometry, in order to reveal the nature of the highly oxidized, S-rich ore-forming magma-hydrothermal system.

These observations indicate that the Qulong magmahydrothermal system was highly oxidized and sulfur-rich. In this study, they confirm a highly oxidized, sulfur-rich magma-hydrothermal system in the Gangdese orogenic setting, which is assumed to be a non-subduction setting.
