Studies of sulfur isotopes of coal or sedimentary rock may not only providesources of sulfur, but also provide some information about sedimentary environment,coalification and diagenesis. Many samples of coal and organic-rich sediments, suchas black shale, contain a considerable content of sulfur that exists in several forms,such as pyrite, monosulfides, sulfates and organic sulfurs. For the various sulfurs,their isotopic compositions can be different in a single sample, for example, theisotopic ratios varied by as many as 30‰ in a sample of coal. To measure

Studies of sulfur isotopes of coal or sedimentary rock may not only providedources of sulfur, but also provide some information about sedimentary environment, coalification and diagenesis. Many samples of coal and organic-rich sediments, suchas black shale, contain a substantial content of sulfur that exists in several forms, such as pyrite, monosulfides, sulfates and organic sulfurs. For the various sulfurs, their isotopic compositions can be different in a single sample, for example, the isotopic ratios varied as as many as 30 ‰ in a sample of coal. To measure
