Early thinning, late persistence, diachronous boundaries, and a regional dichotomy in Mars' young sedimentary rocks [PDF]
Mars’ sedimentary rocks record Gyrs of environmental change. New data enable global analyses of paleo-environment relevant physical properties of these rocks, including layer thickness and accumulation rate.
