Southern Iceland glacial rivers
Iceland, Islande
Rivers and surface water
- Type
- River or surface water
Rivers on basalt (basalt -0.35 ‰); island mean +0.63 ± 0.38 ‰ (n = 20). No glaciated catchment exceeds +0.8 ‰, against four out of seven non-glaciated ones; bedrock age plays no role. Outlets of Vatnajökull and Mýrdalsjökull. Indicative coordinates (centre of the region), no position per river in the paper.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −0.08 ± 0.04 ‰ | 1 | filtered river water (dissolved silicon), Skaftafellsá Skaftafellsá (IS 23): 1.7 Ma bedrock, 208 km² catchment, 100 % glaciated. Fully glaciated catchment: the only negative value of the study. | Georg et al. (2007), Silicon isotope variations accompanying basalt weathering in Iceland… | |
| 0.41 ± 0.04 ‰ | 1 | filtered river water (dissolved silicon), Hólmsártn Hólmsártn (IS 25): 0.2 Ma bedrock, 122 km² catchment, 41 % glaciated. Name as printed (probably the Hólmsá). | Georg et al. (2007), Silicon isotope variations accompanying basalt weathering in Iceland… |
