Remnant of Unconformable Deposit in Electris

The Electris region of Mars contains some interesting features, such as the raised-relief blocks of material visible in this image.

One goal of this observation is to try to determine the origin of what’s called the “mantling deposit.” How was this deposit placed here? What types of geologic processes have acted to form the deposit? An image at high resolution can help provide details on the thickness and subtle variations within this deposit that can give us information on its origin and what erosional processes it has experienced.

This caption is based on the original science rationale.
