Silie versus carbonate weathering in Iceland: New …

Abstract Several studies have measured riverine fluxes of Ca and carbonate alkalinity in Iceland with the aim of quantifying the role of basalt weathering in the long-term carbon cycle. A major assumption is that all of the Ca and alkalinity originates from the dissolution of Ca-bearing silie minerals, such as plagioclase and clinopyroxene.

Carbonates in the earth - /a>

Carbon dioxide is also soluble in the silie melts that are present at great depths and temperatures below the surface. The solubility depends on conditions of pressure, temperature and composition of the melt. The amount is fifty times less than the amount of water that …

30/9/2007· We have taken the chments from western and central Iceland to represent carbonate-free rivers and estimated (Ca/Na) sil = 0.67 ± 0.17 (± 1σ SD). The Ca sil correction implies that ∼ 46% (IS 16), ∼ 73% (IS 17), and ∼ 81% (IS 22) of the Ca is derived from carbonate dissolution.
