Rivers and surface water
- Type
- River or surface water
River crossing from north to south the Tethyan sedimentary series (carbonates, evaporites of the Mustang graben), the High Himalayan Crystalline and then the Lesser Himalaya. Rose et al. (2000): δ11B decreasing downstream in the Tethyan series, from +23.8 to +9.9 ‰, then rising to +18.3 ‰ in the Lesser Himalaya; boron mostly from evaporite dissolution (9.4 to 64.4 % of dissolved B), partly brought by hot springs. Without published coordinates.

| 16.5 ± 5.4 ‰ | 9.9 / 29.4 ‰ | 12 | main-stream water (dissolved boron) Mean and standard deviation recalculated from 12 analyses, +9.9 to +29.4 (LO49 +23.8; NAG21 +29.4; LO101 +17.1; NAG30 +15.1; NAG32 +11.8; NAG34 +9.9; NAG39 +13.0; NH10 +14.2; NAG43 +13.6; NAG45 +14.4; NAG5 +18.3; LO306 +17.4). Elevation, dissolved B and 1σ uncertainty: LO49: 3550 m, 5.92 µmol/l, ± 1.1 ‰; NAG21: 2790 m, 5.55 µmol/l, ± 0.7 ‰; LO101: 2530 m, 5.09 µmol/l, ± 0.4 ‰; NAG30: 2626 m, 5.27 µmol/l, ± 1.5 ‰; NAG32: 2530 m, 5.46 µmol/l, ± 2.0 ‰; NAG34: 2500 m, 3.52 µmol/l, ± 1.5 ‰; NAG39: 1450 m, 3.89 µmol/l, ± 1.9 ‰; NH10: 1180 m, 4.26 µmol/l, ± 0.2 ‰; NAG43: 1180 m, 2.22 µmol/l, ± 0.9 ‰; NAG45: 740 m, 1.85 µmol/l, ± 0.8 ‰; NAG5: 460 m, 0.83 µmol/l, ± 1.9 ‰; LO306: 305 m, 0.65 µmol/l, ± 2.0 ‰. NAG21 is the evaporite end-member of the authors' mixing model. | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… |
| 11.7 ‰ | 1 | Miristi tributary water (dissolved boron) Single analysis (NAG41). 1490 m, 0.19 µmol/l B, ± 0.7 ‰ (1σ). Highly carbonate tributary: about 70 % of dissolved B would come from carbonates. | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… | |
| −7 ‰ | 1 | Narsing Khola tributary water (dissolved boron) Single analysis (LO96). 2900 m, 28.68 µmol/l B, ± 2.2 ‰ (1σ). Lowest value of the study, with the highest B and K of the rivers (880 mg/l dissolved load). | Rose et al. (2000), Fractionation of boron isotopes during erosion processes: the example… |
