Niger ('Bani' sample)
Rivers and surface water
- Type
- River or surface water
Dissolved silicon heavier than igneous rocks (-0.3 ± 0.3 ‰), a sign of fractionation during weathering and clay formation; the rivers studied by De La Rocha et al. (2000) give +0.8 ± 0.3 ‰ (n = 8). The source only states 'Niger, Bani', without saying whether this is the Bani tributary or a place name. Site not precisely located: the source gives no coordinates.
