This nitrogen could derive from the mantle, and metabolized by chemosynthetic communities living close to hydrothermal systems, in fully agreement with the depositional environments of the N-host rocks .…”

Yet, they also showed its limitations which are mainly due to our poor understanding of the origin of N in sediments and of the geochemical behavior of nitrogen during early diagenesis [Freudenthal et al, 2001;Lehmann et al, 2002] weathering [Busigny et al, 2005] and metamorphism [Busigny et al, 2003].…”

[1] To quantify and localize nitrogen (N) and carbon (C) in Archean rocks from the Marble Bar formation, Western Australia, and to gain insights on their origin and potential biogenicity, we conducted nuclear reaction analyses (NRA) and carbon and nitrogen isotope ratio measurements on various samples from the 3460-Myr-old Fe-rich Marble Bar chert. The Marble Bar chert formed during the alteration of basaltic volcanoclastic rocks with Fe-and Si-rich hydrothermal fluids, and the subsequent precipitation of magnetite, carbonates, massive silica, and, locally, sulfides. At a later stage, the magnetite, sulfides, and carbonates were replaced by Fe-Mn-oxyhydroxides. Nuclear reaction analyses indicate that most of the N and C resides within these Fe-Mn-oxyhydroxides, but a minor fraction is found in K-feldspars and Ba-mica dispersed in the silica matrix. The N and C isotopic composition of Fe-oxides suggests the presence of a unique biogenic source with d 15 N AIR values from +6.0 ± 0.5% to 7.3 ± 1.1% and a d 13 C PDB value of À19.9 ± 0.1%. The C and N isotope ratios are similar to those observed in Proterozoic and Phanerozoic organic matter. Diffusion-controlled fractionation of N and C released during high combustion temperatures indicates that these two elements are firmly embedded within the iron oxides, with activation energies of 18.7 ± 3.7 kJ/mol for N and 13.0 ± 3.8 kJ/mol for C. We propose that N and C were chemisorbed on iron and were subsequently embedded in the crystals during iron oxidation and crystal growth. The Fe-isotopic composition of the Marble Bar chert (d 56 Fe = À0.38 ± 0.02%) is similar to that measured in iron oxides formed by direct precipitation of iron from hydrothermal plumes in contact G 3

“…Biologically-mediated nitrogen burial goes back to at least 3.8 Gyr, potentially affecting the atmospheric N 2 reservoir (Goldblatt et al, 2009;Johnson and Goldblatt, 2015;Papineau et al, 2005;Som et al, 2016;Stüeken, in press;Stüeken et al, in review). Furthermore, biological N 2 O production may have been pronounced in the Proterozoic and possible in the early Paleozoic (Section 5.5, Buick, 2007a;Roberson et al, 2011).…”

Positive values up to +12.2‰ from rocks of similar age are most commonly interpreted as reflecting metamorphic overprinting, which is known to increase δ 15 N (Papineau et al, 2005;Thomazo and Papineau, 2013). The entire range of values could in theory also result from biological processes ( Table 1).…”

Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on biological productivity in the modern ocean. Accurate reconstructions of the evolution of life over the course of the last four billion years therefore demand a better understanding of nitrogen bioavailability and speciation through time. The biogeochemical nitrogen cycle has evidently been closely tied to the redox state of the ocean and atmosphere. Multiple lines of evidence indicate that the Earth"s surface has passed in a non-linear fashion from an anoxic state in the Hadean to an oxic state in the later Phanerozoic. It is therefore likely that the nitrogen cycle has changed markedly over time, with potentially severe implications for the productivity and evolution of the biosphere. Here we compile nitrogen isotope data from the literature and review our current understanding of the evolution of the nitrogen cycle, with particular emphasis on the Precambrian. Combined with recent work on redox conditions, trace metal availability, sulfur and iron cycling on the early Earth, we then use the nitrogen isotope record as a platform to test existing and new hypotheses about biogeochemical pathways that may have controlled nitrogen availability through time. Among other things, we conclude that (a) abiotic nitrogen sources were likely insufficient to sustain a large biosphere, thus favoring an early origin of biological N 2 fixation, (b) evidence of nitrate in the Neoarchean and Paleoproterozoic confirm current views of increasing surface oxygen levels at those times, (c) abundant ferrous iron and sulfide in the midPrecambrian ocean may have affected the speciation and size of the fixed nitrogen reservoir, and (d) nitrate availability alone was not a major driver of eukaryotic evolution.
