Antarctic permafrost comprises fluvial and eolian ice cemented sediments that are coarse- to medium-grained sands and fine gravels.
It is also used for dating the deposition of geological sediments after they have been transported by air (eolian sediments) or rivers (fluvial sediments).
These sediments consist of eolian quartz, clay minerals, volcanic ash, subordinate residue of siliceous microfossils, and authigenic minerals such as zeolites, limonite and manganese oxides.
Eolian processes are major factors in shaping desert landscapes.
Also, eolian sedimentation can produce high rates of sediment accumulation.
The smooth floor material is thought to be composed of fluvial material and/or eolian features covering an otherwise rough and jumbled terrain.
Degraded and infilled impact craters record variations in volcanic, fluvial, and eolian activity over geologic time.
Quartz is present with different morphologies, suggesting eolian (wind-based) and fluvial (river-based) transport.
