I'd like a discussion thread about the geology detatched from the time limits of current MSL threads. We had a 'Geomorphology of Cape York' thread that attracted a lot of interesting posts. How about 'Geomorphology of Gale Crater'? I have one or two ideas but many more questions, and I'd like to post them in a longer-running thread away from the day to day imaging discussion. Any other takers?
For starters, does anybody have a contour map of this place like the one at Meridiani with 5m intervals? ADMIN: You have your wishes fulfilled on UMSF (sometimes) |

There are a couple of other reasons why attributing Mount Sharp as a spring mound will not hold water. The lower half of the mound transitions from phyllosillicates to sulphates but the upper half of the mound is a aeolian deposition. So a spring would not explain Mt Sharp. Further, if this was a spring mound then we are considering a huge volume of water - probably enough to fill the crater given the size of Mt Sharp, which would have almost certainly have resulted in a breach of the Northern crater wall. No such breach exists. Well that's my take anyway.
