Barium isotope compositions and major elemental compositions of river water and sediment from the Irrawaddy and Salween River catchments

This dataset contains major elemental compositions and Ba isotope compositions of filtered river water (tab 2), river sediment (tab 3) and rain samples (tab 4) collected in the Irrawaddy and Salween river catchments. In addition, major elemental compositions and Ba isotope compositions of reference clay samples from the Clay Mineral Society (tab 5) are presented. The river sediment samples were subjected to a 5 stage sequential leaching procedure as described in table 1. Data for tests to this sequential leaching procedure, feature triplicates of step 1 (NH4Cl) are presented in tab 6.
