CRISM: Delta in Jezero Crater

Jezero Crater is a ~45km crater near the Nili Fossae region which is believed to have once been flooded with water. The crater consists of a fan-delta system that deposited rich clays in the area. An important detail for us to compare Mars’s geography to Earth’s; like the Mississippi Delta which found little organisms imbedded into the rock, a sign that there could also have been life imbedded into the Mars rock in the delta region. This occurs because of a “drop off” area; when the water would flow in, the minerals would stop and “drop off” into the bedding, making life and organisms able to embed themselves in the rock.
