Referential significance of sulfur isotopes and separation of S species in black shales of Southwest China

  • Published:
Chinese Science Bulletin

Abstract

The states of S species in black shales are very complex, such as organic sulfur, pyrite sulfur and sulphate sulfur. The mineral microtexture, sulfur content and sulfur isotope can indicate the formation conditions and diagenetic processes of the black shales. The S species are separated perfectly and the relation between the content, mineral microtexture and sulfur isotope composition of the sulfur mineral is assessed. These complementary approaches provide people a new insight into the formation conditions of the black shales and redox conditions of Precambrian and Cambrian in Southwest China.
