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) |

In the conclusion section of the abstact for Anderson and Bell III: Mars 5, 76-128, 2010 open access paper,
there is the following sentence -"Some layers in the mound are traceable for >10 km, suggesting that a spring mound origin is unlikely." My understanding of that would be that Mt Sharp was not cemented together by underground (upwelling) mineral water flows during, I guess, - the period when Gale crater was buried in sediment. Because earlier it is said "The rim of Gale Crater is dissected by fluvial channels, all of which flow into the crater with no obvious outlet." As well as, I guess, that hot springs would be variable in flow, time and location? After doing some Googling apparently hot spring can create mounds using nothing but precipitated minerals. However; I don't now how that would relate to the 10 km layers. Would be enough to say that a mound with many layers wasn't created by hot springs? Or am I completely misunderstanding what the sentence is trying to communicate? |
