Oooooh, you're pretty...
Might be here a while, you think? Edit: better colours on this amended version, I think... http://twitpic.com/apn9s1/full -------------------- |

Bill: I think the clastic unit underlying the basal Burns formation but overlying the Endeavour ejecta is being unofficially called the Deadwood formation after the target of that name from around sol 2770 or so (near Homestake). It's not exactly what you are talking about, but close. It was discussed in a recent paper that I can't put my fingers on at the moment, but I will try to find it for you.
ngunn: I think I would have to agree with you regarding garnet schist. As much as I'd love to see it, I don't think Mars has been tectonically active enough to have generated much in the way of schist or gneiss. Right now I find myself agreeing with centsworthII. They look like blueberries to me, though they are on the ragged edge of resolution in these images. Whatever they are, they are embedded in the rock and not just loose granules lying on top. They are resistant to erosion and they are at the head of some mini-yardangs on the surface of the rock, as we have frequently seen with the blueberries out on Meridiani Planum. We should be able to determine if they are hematite concretions in short order. There is an image set coming from sol 3063 with a full set of right filters... pancam_Milnet_L234567Rall... If Milnet is an image of a part of this outcrop, as I suspect it will be, a quick IR ratio image should identify any hematite that may be present. -------------------- ...Tom

i tried to stitch a group of these frames together for a 3D, made a headache for the eyes instead! Spectacular outcrop here. The overhanging rock near the top has a nice white vein in it. The rock near the bottom also has such a vein. Perhaps it rolled off eons ago.
And a thanks for the great color panos of these rocks already posted! Really nice work. |
