- Type
- Stratified Neogene lacustrine borates (colemanite and ulexite)
Miocene lacustrine basin with stratified ulexite and colemanite levels, the latter derived from inyoite diagenesis according to the phase diagram of Christ et al. (1967). Oi et al. (1989): colemanite close to the calculation (-9.1 ‰ for a +3.7 ‰ solution), ulexite much heavier than predicted (-7.6 ‰), implying a pH of about 8.3. Sample depths unknown. Indicative coordinates, not published in the article.
