Isotopic Constraints on the Late Archean Carbon Cycle from the Transvaal Supergroup along the Western Margin of the Kaapvaal Craton, South Africa
(Elsevier, 2009)Few existing studies illuminate the operation of the carbon cycle before the rise of atmospheric oxygen circa 2400 million years ago. Stable carbon isotopic measurements of shallow stromatolitic carbonates (~0 [parts per ...
