Distribution and source identification of dissolved sulfate by dual isotopes in waters of the Babu subterranean river basin, SW China
Sulfur and oxygen isotopes were employed to identify SO(4) (2−) sources in surface water and groundwater in the Babu subterranean river basin (BSRB). Our study revealed SO(4) (2−) enrichment in the BSRB waters compared with adjacent areas. The SO(4) (2−) in some samples originated mainly from precip...

| Sumario: | Sulfur and oxygen isotopes were employed to identify SO(4) (2−) sources in surface water and groundwater in the Babu subterranean river basin (BSRB). Our study revealed SO(4) (2−) enrichment in the BSRB waters compared with adjacent areas. The SO(4) (2−) in some samples originated mainly from precipitation; in others, it was derived mainly from sulfide dissolution in coal seams or from gypsum dissolution. In the water at the subterranean river exit, 13% of SO(4) (2−) originated from precipitation, 40% from sulfide oxidation in coal seams, and 47% from gypsum dissolution. |
