Intriguing signals have been detected by the Perseverance rover from the floor and fan top of the Jezero crater on Mars. Laboratory investigations provide insight into the origin of these signals, identifying aromatic organic molecules — polycyclic aromatic hydrocarbons — preserved in sulfates.

This paper shows that amino acids and amines can be preserved for geologically long periods in sulfate mineral matrices, suggesting that sulfate minerals should be prime targets in the search for organic compounds on Mars.

This paper reports analyses of the Tissint Mars meteorite, revealing the presence of aromatic hydrocarbons and sulfur-containing species, along with sulfates and perchlorates.
