Sulfate minerals and organic compounds on Mars | …

Abstract. Strong evidence for evaporitic sulfate minerals such as gypsum and jarosite has recently been found on Mars. Although organic molecules are often codeposited with terrestrial evaporitic minerals, there have been no systematic investigations of organic components in sulfate minerals. We report here the detection of organic material ...

2019-6-14 · 1 Introduction. The presence of evaporitic minerals, such as halite (NaCl) and gypsum (CaSO 4 •2H 2 O), on a planet can be interpreted as evidence that wet conditions existed in the planet''s geological history. For example, sedimentation of evaporites is an inevitable outcome when a lake evaporates under playa-like conditions (e.g., Komatsu et al., 2007).
