Nevertheless, the detailed mechanisms as related to the interaction between nitrogen compound in the ascending fluid and rock during the path through the lithosphere are not fully understood. Stable nitrogen isotopic ratios have still been proven to be a significant tracer in different geochemical environments (Busigny and Bebout, 2013; Freudenthal et al., 2001; Holmes et al., 1999; Lehmann et al., 2007; Li et al., 2007; Melchiorre and Talyn, 2014; Philippot et al., 2007; Robinson et al., 2012; Tesdal et al., 2013). Many of the studies about nitrogen isotopic ratios of MORB on the basis of diamond containing nitrogen species have been reported with a wide range of d15N values from –25 up to +15‰, while the d15N values of nitrogen in gloMineral nitrogen isotope signature in clay minerals formed under high ammonium environment conditions in sediment associated with ammonium-rich sediment-hosted hydrothermal system
