<jats:p> 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. H <jats:sub>2</jats:sub> O, SO <jats:sub>2</jats:sub> , CO <jats:sub>2</jats:sub> , and O <jats:sub>2</jats:sub> were the major gases released. Water abundance (1.5 to 3 weight percent) and release temperature suggest that H <jats:sub>2</jats:sub> O 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 CO <jats:sub>2</jats:sub> . Evolved O <jats:sub>2</jats:sub> is coincident with the release of Cl, suggesting that oxygen is produced from thermal decomposition of an oxychloride compound. Elevated δD 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. </jats:p>
