Sediments in Ladon Basin
ESP_032297_1595  Science Theme: Sedimentary/Layering Processes
This image shows light-toned layered deposits at the contact between the Ladon Valles channel and Ladon Basin.

These deposits could either be fluvial sediments transported along Ladon Valles when water carved out this channel, or they could be sediments deposited in Ladon Basin, perhaps when a lake existed here. Some of these light-toned deposits have mineral signatures consistent with clays, indicating favorable water conditions for life.
