- Groundwater
Salt lake at 4522 m in a faulted basin of the Bangong-Nujiang suture, 8 km east of Siling Co, divided into three lakes (Bangor Co I to III); arid climate (less than 150 mm rain, 2200 to 2500 mm evaporation). Coordinates not published. Ca-Mg-HCO3 springs south of the lake and overflow waters of spring BG-04 (BG-05, BG-06); low-δ11B end-member supplying more than 60 to 90 % of the lake boron in the authors' mixing model.
