Geothermal systems of Java (Sunda arc) sampled in 2012-2013 by Purnomo et al. (2016); Quaternary volcanic systems receive magmatic fluids, fault-hosted systems in the south of the island mostly neutral waters. Coordinates not published (map only). Sari Ater geothermal system and Kawah Domas crater.

Standard : NIST SRM 951
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 2.4 ‰ | 1 | hot spring water (dissolved boron) Single analysis (J36 Sari Ater). 46.6 °C, pH 2.0, 2.07 mg/L B. | Purnomo et al. (2016), Boron isotope variations in geothermal systems on Java, Indonesia,… | |
| 5.54 ‰ | 1 | acid sulphate crater lake water (dissolved boron) Single analysis (J72 Kawah Domas). 85 °C, pH 1.8, 2.68 mg/L B; drained to the nearby river, hence less evaporation than at Sikidang. | Purnomo et al. (2016), Boron isotope variations in geothermal systems on Java, Indonesia,… |
