Degassing of reduced carbon from planetary basalts

on a lunar basalt composition, we confirm that carbon dissolves as carbonate at an fO 2 higher than -0.55 relative to the iron wustite oxygen buffer (IW-0.55), whereas at a lower fO 2, we discover that carbon is present mainly as iron pentacarbonyl and in smaller

Based on a simple steady-state balance equation of the external input of dissolved iron over the plateau, the fertilization of iron inferred by using dissolved Co as a tracer of basalt sources is estimated to be 28 × 10 2 ± 21 × 10 2 t yr-1 in surface waters of the Kerguelen Plateau. This estimate is consistent with preceding ones (Zhang et ...

Bioleaching of ilmenite and basalt in the presence of iron ...

This is likely because the Fe(II) leached from the basalt was immediately oxidized by A. ferrooxidans, and precipitated into Fe(III) phases which causes a change in the equilibrium of the system, i.e. Le Chatelier's principle. Iron(II) in the abiotic experiment was allowed to build up in solution which led to a decrease in its overall release rate.
