In 2019, Curiosity detected the largest amount of methane ever found on Mars. The V/M ratio can, therefore, be used as an index of "dispersion", uniform distributions having a V/M ratio less than unity and clustered distributions greater than unity.
The dimension of these aggregates, their unusual structure and distribution and the lacking of net contact with the host sediments, that'suggests that they are not transported/deposited elements, but that their formation was inside the sediment, after deposition, due to local cementation and/or grain rearrangement; conditions likely to be present during diagenesis and still existing in lake waters. NASA's Curiosity rover has found complex organic molecules, which could have been made by ancient life forms. More recently, the presence of chloromethane and dichloromethane, as markers of organic matter on Mars, were confirmed by SAM on Curiosity [65].
