Figure 11From: Abiotic ammonium formation in the presence of Ni-Fe metals and alloys and its implications for the Hadean nitrogen cycleNH4+ formation from N2 in Hadean hydrothermal systems. Fluxes are calculated as a function of N2 conversion between 1 and 10%. NH4+ formation from NO2-/NO3- is not included in these calculations.Back to article page
