Curiosity’s Samples from Martian Crater Strongly Depleted in Carbon-13, Researchers Say planetaryscience space science

Spectrographic analysis of a portion of the reduced carbon produced by this pyrolysis showed a wide range of carbon-12 and carbon-13 amounts depending on where or when the original sample formed.“The samples extremely depleted in carbon-13 are a little like samples from Australia taken from sediment that was 2.7 billion years old,” Professor House said.
“Every couple of hundred million years the Solar System passes through a galactic molecular cloud,” Professor House said. The dust would have deposited on top of the ice and would then need to remain in place once the glacier melted, leaving behind a layer of dirt that included the carbon. This explanation is plausible, but it requires additional research.
