  • A molecular isotopic study of 13C-enriched organic

    2001-2-1  Both the organic matter in the saltern pond sediment and the Northern Apennines marl are also relatively enriched in 13 C (δ 13 C TOC =−15.0‰ and −18.0‰, respectively). The results demonstrate that compound-specific isotope analysis, in contrast to bulk isotopic analysis, can identify CO 2 -limited ecosystems that exist presently and have existed in the past.

    2019-11-1  Three basic models can account for the accumulation of organic matter in organic-rich sediments, i.e., black shales: (1) increases in the organic productivity (Pedersen and Calvert, 1990; Sageman et al., 2003; Tyson, 2001, 2005; Wei et al., 2012); (2) enhancement of organic matter preservation, which may be related to reducing conditions (Demaison and Moore, 1980; Arthur and

    2014-12-1  These results suggest that where 15N enrichment occurs due to fractionating loss pathways, the isotope effects are primarily transmitted to immobilized N, forming 15N enriched stabilized OM. This further explains earlier findings that the δ15N of soil OM represents an integrated indicator of losses, reflecting the intensity and duration of pastoral agriculture.

    1995-5-1  A highly stratified water column resulted in the accumulation of isotopically depleted carbon as organic matter in the deep ocean, while the shallow ocean became progressively enriched in ~3C. Evapo- ration of an already enriched shallow water mass may have resulted in the values measured here in carbonates and organic matter.

    Carbonaceous chondrites comprise a unique subset of meteorites. Two classes of carbonaceous chondrites, the so-called CI1 and CM2 chondrites, are particularly interesting, in part because of their relatively high carbon content and the fact that most of this carbon is present as organic matter. This material is largely macromolecular but also contains a complex mixture of organic compounds.
