About this work
Sediments rich in hydrated sulfates may have filled central Valles Marineris, but debates persist as to how these deposits grew or formed. If they formed from deposition in a deep lake then the layers should be nearly horizontal. If the layers formed from airfall deposits such as volcanic pyroclastics or windblown dust, then the layers should drape over the pre-existing topography. Another possibility is that the layers were deformed by slumping.
