Abstract
The carbon isotopic composition of Proterozoic organic matter has been studied as a function of elemental H/C ratio. Kerogen samples which have experienced various degrees of postdepositional thermal alteration show a correspondingly wide spread of δ13C values. Setting a minimum H/C threshold of 0.2 to eliminate the kerogens of highest rank immediately results in a marked contraction in the range of δ 13C. Analysis of the time-dependence of these data reveals a smooth trend of increasing δ13C from an Early Proterozoic average of — 34 %o PDB to about — 30.5%o for the Middle Proterozoic. This contrasts markedly with the record of Proterozoic carbonates, which typically average near 0%o PDB. Several explanations are offered for this trend. Firstly, a long-term decline occurred in the partial pressure of atmospheric CO2 during the Proterozoic. An accompanying development of biochemical pumps, which raise the internal CO2 concentrations of photoautotrophs and allow the maintenance of high levels of carbon fixation, would cause a partially closed system with respect to external CO2 and a reduction in 13C fractionation. Alternatively, or perhaps additionally, evolutionary pressures toward optimizing the kinetic parameters of the major carboxylating enzyme RUBISCO may have been accompanied by a reduction in the enzymic discrimination against 13C. Late Proterozoic kerogens display substantial isotopic variability. This most likely reflects secular changes in the burial rates of organic versus carbonate carbon.
