@65dBnoise yes, not so extreme diffs, but 3 billion+ years is a loooong time. Take that rock for example (assuming it's of volcanic origin if the color scale says anything): I can still imagine it having been transported long distances in large floods (rounded sides at the bottom) and having spent some Myrs under water with corresponding alteration. Its final location & aspect can be a combination of erosion and dislodgment.

In 3 billion years anything can happen, almost everywhere. I made a case for these rocks because I don't remember seeing others cracked like these in Jezero. Maybe I'm wrong.

I think more data is needed and from a lot more places, maybe from outside the delta too, to build a plausible theory about this place. Initially expected were sedimentary rocks, but instead igneous rocks were found in Seitah. And now cracked open rocks here. Maybe that's normal. IANAG™
