Crater counting is a widely applied methodology for dating large areas of planetary surfaces, but is difficult to apply the method to constrain the durations of stratigraphic unconformities. Unconformities with exhumed craters are thought to indicate …
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 …
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 …
