So the layering-like texture we are seeing is actually wind erosion, not layering? Like micro-yardangs? Seems that way to me Mark. This looks like a lithic breccia along the lines of Tisdale rather than a suevite. It may be my imagination but are there some wind tails where clasts protected the matrix from what would have been a NW wind? I don't think it is possible to differentiate between breccia deposited before the Endeavour impact in an uplift rim or as large chunks of ballistic ejecta from the impact and new breccia formation arising from the impact. |
