Here are a few renders of a sandstone desert. Thinly bedded sandstones deposited in a rhythmic process. Some beds horizontal, some dipping at various angles. A band of carbon rich material visible in one render. Low flat areas partly covered in a salty crust indicating onetime presence of a lake or seaway.
Carbon band.
I think the main form of erosion here is definitely wind, hence the lack of scree and rubble. Sand particles are dislodged from the rock face and simply blown away, scouring and sculpting as they go. Presumably there is a repository for this windblown sand, a nearby erg perhaps...
