Is the Jezero Crater a landscape of an wind-eroded glacier moraine?

(and the delta is an eroding remnant of the moraine)

The hope that rover Perseverance's mission will find traces of life will not come true. The photos available so far from the mast- camera suggest that the landsscape in the Jezero crater is a wind-eroded glacier moraine, and the delta is the eroded remnant of this glacier moraine. The most deposits in the delta are stratified, but contain a lot of boulders. This boulders are not rounded by running water.The thin layered deposits in the delta occure as stacked blocks, with discordances between. That can only mean periodic activities of the glacier. The thin parts in the moraine probably contain minerals from completely disintegrated volcanic rocks. It could also be pure volcanic ash *. Due to the fact that no deposits caused by flowing water was detected to date, it is assumed that the moraine only can be created by a dry ice glacier (Frozen Carbon Dioxide). The delta is not a lacustrine fan of a river that was flown into a lake.

*New: the striking stratification in the blocks is primary and not the result of a secondary deposition in the delta.

Fluvial cross-bedding in the delta is that NOT. This are secondary structures that were come by periodic ice pressure
