Carbon Isotope Abundance in Meteoritic Carbonates

Science, 1963
The C 13 /C 12 ratio in the carbonate minerals of Orgueil, a carbonaceous chondrite, is 6 percent greater than the ratio in any known terrestrial carbon. The effect may be produced by a chemical isotope fractionation involving processes not common on earth, or it may be the result of ...

Deuterium Isotope Effect on Carbon Isotope Fractionation in Photosynthesis

Science, 1967
Plants grown in D 2 O show a decreased tendency to fractionate carbon-13 during photosynthetic incorporation of carbon dioxide. The isotopic ratio C 13 /C 12 of the tissues of deuterated plants appears to be proportional to the deuterium content of the tissue.

The carbon-isotope signature of diagenetic carbonates

2020
<p>Diagenetic carbonates often show large variations in their carbon isotope compositions. Variations are mainly the result of isotope fractionation effects during microbial metabolic processes, and these processes themselves may induce carbonate formation.

Carbon Isotopes and Microbial Sediments

2000
Microbial sediments of the biolaminated type, generated by the matting behavior of preferentially prokaryotic microbenthos, commonly carry the isotopic signatures of both the primary microbial biomass and of the carbonate of the surrounding sediment matrix.
