The relatively low concentrations (parts per million level) complicate efforts to constrain the nitrogen speciation and abundance in the mantle and crust. In most silicates, nitrogen occurs as NH4+ (substituting for K+), whereas its speciation in hydrous fluids and silicate melts can vary widely depending in large part on redox conditions. Current knowledge of nitrogen isotope fractionation among relevant mineral and fluid/melt phases is limited by the lack of experimental data to confirm theoretical predictions of these fractionations. Modeling of modern and long-term nitrogen cycling on Earth will be advanced by better constraints on the sizes and isotopic compositions of the major crust and mantle nitrogen reservoirs.
