Manganese has been noticed on Mars by the NASA Curiosity rover in a number of locations, however a higher-than-usual quantity has been detected within the Gale crater.
The ChemCam instrument onboard the rover detected the deposits, which point out that the sediments had fashioned in a river, delta, or close to the shoreline of an historic lake.
These sedimentary rocks have bigger grain sizes than what’s typical for the lakebed rocks within the Gale Crater. This might point out that the unique sediments have been fashioned in a river, delta, or close to the shoreline of the traditional lake.
