Tibet (Xizang), Ngari Prefecture, Shiquanhe-Lakkor Co-Yongzhu-Jiali ophiolite melange zone, China
OtherB (Li, K)
- Type
- Boron-rich salt-lake brine
Boron-rich salt lake on the ophiolite melange zone (Jurassic MORB- and arc-type basalts) on the southern flank of the Bangong-Nujiang suture; sampled in winter 2015 (Li et al., 2022). Coordinates not published (map between 31°50' and 32°10' N, 83°45' and 84°15' E). Boron-rich salt lake west of Lakkor Co, with a slightly higher water level and no surface connection to it.
