Martian concretion sizes predicted from two independently constrained inputs: atmospheric dust grain size and obliquity-forced wetting duration

This paper predicts the sizes of Martian concretions using two independent inputs: the size of atmospheric dust grains and the duration of obliquity-forced wetting. The study identifies solid concretions at multiple widely separated sites on Mars, all within the millimeter size range, despite differing cement mineralogies. This research contributes to understanding past water activity and geological processes on Mars, which is crucial for future human missions and resource exploration.
