Isotopc compositions of strontium in river river water of Guizhou karst areas, China

摘要

We have carried out a study on the variation of strontium isotope composition of river waters, wujiang and Yuangjiang River, in karst areas of Guizhou Province, china. The results ob- tained permit us to characterize the geochemistry of the river draining karst terrain and obtain a better understanding of main controls of catchment geology, chemical weathering of different rocks, and evaluate impact of human activities on the environment.
