13C‐rich marbles from the Proterozoic Einasleigh metamorphics, northern Queensland

Abstract
Four samples of dolomitic marble from the Proterozoic Einasleigh Metamorphics of northern Queensland contain unusually high δ13C (5.1 to 5.9‰ PDB). A hyper‐saline depositional and diagenetic environment for these rocks adequately explains the available field and chemical evidence, and the heavy carbon signature.
