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). Single springs of four volcanic systems.
δ11B in ‰ (per mil) Values of the same system
Standard : NIST SRM 951
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 4.73 ± 6.33 ‰ | −0.95 / 12.81 ‰ | 4 | hot spring water (dissolved boron) Mean and standard deviation recalculated from 4 analyses, -0.95 to +12.81 (J21 Segaran (Lamongan) +6.67; J54 Cileungsing (Tampomas) -0.95; J39 Cibolang (Pangalengan) +0.40; J55 Darajat +12.81). 45 to 69 °C, 5.3 to 21.4 mg/L B; Darajat is acidic (pH 2.8). Segaran would have gained 11B by adsorption onto minerals according to the authors. | Purnomo et al. (2016), Boron isotope variations in geothermal systems on Java, Indonesia,… |
