Sulfur isotopic composition of Yellow and Yangtze rivers and uplift of the Qinghai-Xizang plateau

摘要

The sulfur isotopic oomposition of dissolved sulfate in any rivers has been recognized as a mixture of the sulfur derived from the soil, bedrock and the atmosphere. The measurement of the sulfur isotopic composition in a river water can provide background information on the biogeochemical cycling of sulfure in the river basin. So far, however, little work has been done on sulfur isotope in the watersheds of the major rivers of the world. In particular, no information of the sulfur isotope of the major rivers in Asian continent has been reported in western literature.
