OtherB

Type: Quaternary salar borates (ulexite)

Eastern Puna salar; Quaternary borates (mostly ulexite, minor borax or tincalconite) as massive beds or nodules up to 1.5 m thick (0.3 m on average), with carbonate, gypsum and halite, deposited by former thermal springs along fractures at the salar margin. Samples from the top 30 cm (Kasemann et al., 2004). Surrounded by Precambrian-Paleozoic magmatic and metamorphic basement. Coordinates not published (map only).
