Alternating wet and dry depositional environments recorded in the stratigraphy of Mt Sharp at Gale Crater, Mars

The Curiosity rover is exploring Hesperian-aged stratigraphy in Gale crater, Mars, where a transition from clay-bearing units to a layered sulfate-bearing unit has been interpreted to represent a major environmental transition of unknown character. We present the first description of key facies in the sulfate-bearing unit, recently observed in the...

Because these features often resemble patchy frost residue rather than three‐dimensional blocks, more evidence is needed to support...
