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) |

I'm sorry elakda for making it sound too you like i'm talking about the Flintstones.
Bedrock on Mars as far as I know, now you correct me if I'm wrong: basalt. Not to be confused will the surface photos of conglomerate and limestone sediment slabs we see. We see chucks of basalt everywhere BUT what we don't see is the primal intact basalt global covering if there is one. Basalt like all the surface basalt littering the surface indicates there should be basalt in the floor a deep crater it should be revealed or even to have been blasted clean through. Bedrock is not compressed sediment. At lest not the type of bedrock I was talking about. NASA will be drilling for subsurface basalt NMHO. |

...Bedrock is not compressed sediment. At lest not the type of bedrock I was talking about. This mission is specifically designed to study the compressed sediments of Mount Sharp and the surrounding area. Not to look for subsurface basalt. The drill goes no deeper than a couple inches. The landing site was chosen because of the deep layered stack of compressed sediments that could be seen in Mount Sharp, not because of any sub-surface basalt.NASA will be drilling for subsurface basalt.... Edit: Here is a short description of why MSL went to Gale Crater. Notice, no mention of basalt. |
