Work summarized by Hayes (1993) and Hayes (2001) has demonstrated that the final carbon isotope composition of naturally synthesized organic matter depends on a complex set of parameters. (1) the C-content of the carbon source, (2) isotope... [Pg.51]

Newer instrumental methods of potential utility in organic analysis of environmental and geological biomarkers are compound specific isotope analysis (CSIA) and carbon-14 dating with accelerator mass spectrometry (AMS). CSIA provides the carbon isotope composition of individual... [Pg.88]

Thus available data on the variations in the carbon isotopic composition in Precambrian carbonates, graphitites, and organic matter confirm the important role of organic processes in the formation of the BIF, especially in the Proterozoic. In the Archean, apparently, organic life was more limited and processes of chemical deposition of carbonates prevailed. [Pg.75]
