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展开更多
