basement Huangmaqing Formation suggests that the pyrites with
extremely negative d34S values was derived from organic matter
in the Huangmaqing Formation, whereas the pyrites with extremely positive d34S values sourced sulfur from evaporites within
the Qinglong Group. In summary, the wide range of sulfur isotopic
compositions of sulfides within the Baixiangshan deposit suggests
a mixed sulfur source that incorporated magmatic sulfur, sulfur
derived from the surrounding country rocks, and sulfur generated
by TRS at temperatures of 200–300 C.
