The 43 lakes are Pengcuo, Bamucuo, Banggucuo, Amucuo, Qiagangcuo, Biluocuo, Caiduochaka, Eyacuo, Qixiangcuo, Pusaiercuo, Guogencuo, Ga'acuo, Duijiali Lake, Guopuke, Chirikucuo, Cuonongque, Niandengnabucuo, Cuowenbu, Tawakalecuo, Cuoguoguo, Mudicuo, Donggucuo, Lagancuo, Mapamyumco, Peikuco, Cuojilong, Zhaxicuo, Kunchukucuo, Bala, Kahucuo, Lemaca, Chamcuo, Bietang, Alucuohu, Sijiahu, Meimacuohu, Mangcuo, Wobacuo, Matouhu, Shouxinghu, Bangdacuohu, Puercuo and Yueyahu. A total of 169 water samples were collected, with no fewer than 2 samples obtained from each individual lake. The contents of 13 targeted elements, namely K, Na, Ga, Mg, Cl, Li, Br, B₂O₃, CO₃²⁻, SO₄²⁻, HCO₃⁻, Rb and Cs, were measured, with the units reported in g/L or mg/L. All sample testing and analytical work were completed at the Key Laboratory of Mineralization and Resource Assessment, Ministry of Natural Resources, Institute of Mineral Resources, Chinese Academy of Geological Sciences. For K (detection limit: 4.5 μg/L), Na (6.36 μg/L), Ca (6.61 μg/L), Mg (1.94 μg/L), B₂O₃ (1.25 μg/L), Li (0.33 μg/L), Rb (0.04 μg/L) and Cs (0.03 μg/L), inductively coupled plasma mass spectrometry (ICP-MS) was adopted, with the relative deviation of all tested samples ≤ 20%. For Cl (detection limit: 0.007 mg/L), Br (0.016 mg/L) and SO₄²⁻ (0.018 mg/L), ion chromatography was used, with the relative deviation ≤ 10%. CO₃²⁻ and HCO₃⁻ were determined via hydrochloric acid titration. The measured data are of great significance for clarifying the current reserves of salt lake resources in Tibet, conducting prospective resource assessment and facilitating their development and utilization.
