An earlier exchange with #NASA JPL's engineer Tom Barber, @magicaltrout, resulted in these 3 very comprehensive papers about the geological processes that formed what we see today in #Perseverance's images from Jezero Crater (paper titles in image description):

Lot's of geology for a non geologist to grok 🤓
