| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 7 ± 4.6 ‰ | 1.1 / 11.8 ‰ | 6 | main-stream water (dissolved boron) Mean and standard deviation recalculated from 6 analyses, +1.1 to +11.8 (LO256 +11.0; TRI 15/7 +1.1; TRI 15/8 +7.5; TRI 1/12 +1.7; LO316 +11.8; LO304 +8.7). Elevation, dissolved B and 1σ uncertainty: LO256: 1430 m, 1.39 µmol/l, ± 0.9 ‰; TRI 15/7: 700 m, 0.37 µmol/l, ± 0.9 ‰; TRI 15/8: 700 m, 0.28 µmol/l, ± 1.5 ‰; TRI 1/12: 700 m, 2.22 µmol/l, ± 1.4 ‰; LO316: 465 m, 0.93 µmol/l, ± 2.2 ‰; LO304: 320 m, 1.30 µmol/l, ± 0.8 ‰. The three samples at 700 m bracket the monsoon: from +1.7 ‰ (TRI 1/12) to +7.5 ‰ (TRI 15/8) for 2 µmol/l less B. | Rose et al.

| 26.7 ‰ | 1 | Chake tributary water (dissolved boron) Single analysis (KN95). Elevation, dissolved B and 1σ uncertainty: KN95: 935 m, 0.28 µmol/l, ± 1.0 ‰. Drains only the High Himalayan Crystalline, silica-rich: silicate end-member of the mixing model (+36.9 ‰ after rain correction). | Rose et al.

| 13.4 ‰ | 1 | Bhuri Gandaki tributary water (dissolved boron) Single analysis (LO300). Elevation, dissolved B and 1σ uncertainty: LO300: 410 m, 0.83 µmol/l, ± 1.1 ‰. | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… | |
| 8.9 ‰ | 1 | Seti Khola tributary water (dissolved boron) Single analysis (LO302). Elevation, dissolved B and 1σ uncertainty: LO302: 325 m, 0.46 µmol/l, ± 0.9 ‰. | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… | |
| 19.5 ± 1.5 ‰ | 18.4 / 20.5 ‰ | 2 | Marsyandi tributary water (dissolved boron) Mean and standard deviation recalculated from 2 analyses, +18.4 to +20.5 (NAG24 +20.5; MO2 +18.4). Elevation, dissolved B and 1σ uncertainty: NAG24: 5050 m, 0.09 µmol/l, ± 2.0 ‰; MO2: 600 m, 3.52 µmol/l, ± 2.5 ‰. NAG24, near the source, has B at rain level and is not corrected by the authors. | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… |
