Our goal is to compare textures and determine stratigraphy for these two materials. Enhanced color very useful for mapping units of distinct composition.

Data from other instruments, such as THEMIS and CRISM, imply that chlorides are present here; the CRISM data reveal that iron/magnesium clays are also present.

Layered Bedrock
This un-named crater in southwestern Arabia Terra contains a treasure!
Layered sediments are the key to the puzzle of Martian history. They tell us about the conditions that existed when the sediments were deposited, and how they changed over time.
