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) |

My first thought about the silica enrichment has been a process connected to the hematite enrichment at Vera Rubin ridge, kind of leaching and precipitation cycle. But there are lots of gaps, of course, and those two layers could have formed independently. I don't see an immediate connection to the overlying sulfate layer thus far.
One may also conclude, that we are going to learn more about the details of Martian history, but our understanding of the long-term geological structure doesn't need to be challenged. |
