Beni River (Madeira basin), sediment profiles
Beni basin, Bolivia
Rivers and surface water
- Type
- River or surface water
Purely sedimentary catchment. Depth profiles from the field campaigns of Bouchez et al. (2011) and Dellinger et al. (2014). Aarons et al. (2023): suspended sediment heavier than bedload, which concentrates dense Fe-Ti oxides and zircon; delta49Ti correlated with Al/Zr, with no clear link to depth or modal grain size.
δ49Ti in ‰ (per mil) Values of the same system
Standard : OL-Ti
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 0.206 ± 0.037 ‰ | 0.18 / 0.232 ‰ | 2 | suspended sediment (depth profile) Mean and standard deviation recalculated from 2 analyses, +0.180 to +0.232 (AM01-16 (0 m) +0.232; AM07-06 (7 m) +0.180). Published mean +0.206 ‰. Published mean suspension - bedload offset for this river: +0.044 ‰. | Aarons et al. (2023), Titanium transport and isotopic fractionation in the Critical Zone,… |
