Abstract

Samples from the Rocknest aeolian deposit were heated to ~835°C under helium flow and evolved
gases analyzed by Curiosity’s Sample Analysis at Mars instrument suite. H2O, SO2, CO2, and
O2 were the major gases released. Water abundance (1.5 to 3 weight percent) and release
temperature suggest that H2O is bound within an amorphous component of the sample.
Decomposition of fine-grained Fe or Mg carbonate is the likely source of much of the evolved CO2.
Evolved O2 is coincident with the release of Cl, suggesting that oxygen is produced from thermal
decomposition of an oxychloride compound. Elevated dD values are consistent with recent
atmospheric exchange. Carbon isotopes indicate multiple carbon sources in the fines. Several simple
organic compounds were detected, but they are not definitively martian in origin.
