Layered Deposits

Bedding scale correlation on Mars in western Arabia Terra

Abstract Layered rocks in the Arabia Terra region of Mars preserve a record of the planet’s ancient climate. However, the exact formation mechanism of these rhythmically layered deposits is currently unknown. We previously proposed two distinct …

A fragile record of fleeting water on Mars

The light-toned sedimentary layers that outcrop widely throughout Mars’ Southern Highlands have long been an enigma in uncovering the climatic history of Mars. Although these units seem to contain unique records of fluctuating surface conditions, the …

Regional Correlations in the layered deposits of Arabia Terra, Mars

In the mid-equatorial region of Arabia Terra, Mars, dozens of moderately-sized impact craters (10-100 km diameter) contain layered sedimentary deposits. Previous work has found that these layers are resolvable at the meter scale and that they are …
