Sulfur: A Ubiquitous and Useful Tracer in Earth and Planetary Sciences

摘要: Sulfur is a widely distributed element on Earth and in the solar system. Its multiple valence states (S 2− to S 6+ ) allow it participate numerous geochemical biochemical processes. It may be one of light elements Earth9s core have been crucial formation. an essential component all life likely supported earliest life. geochemistry used understand early evolution atmosphere hydrosphere, serves as monitor volcanic SO 2 H tracer anthropogenic sources sulfur. Recent advances use sulfur isotopes ( 32 S, 33 34 36 S) situ isotopic measurements will help develop stable vital planetary sciences provide applications for understanding inorganic biogenic
