"Whitewater Lake" RAT in colors (from Pancam).

SOL 3090 - front and rear hazcam:




The rear one is scaled down to "hide" the compression artifacts ...

Next to it are two interpretations from SOL 3090 images of the RAT hole. The left one is the false color combination with L3-L6-L7 each filter 100%, the right one is approx. 100%-66%-33% ...

SOL 3087 - MI stitch:



Its not perfect yet ...

Here's my corresponding colour image:



The drill result looks pretty different in colour than the undisturbed surface.

Cheers, Udo

Agreed, looks to me like the red and cyan sides are reversed!

And since the fines provide a pseudo streak test we can be pretty confident that there is no hematite in the mix.

An aside - the drift from greek roots continues. From haematite to hematite, aeolian to eolian, aeon to eon.

I confirm : the layer seems to be really grey, not blue, but as grey as the plaster of Paris...

I'm reading it right now and would like to remark these paragraphs:

The plan ahead is for Opportunity to check out other sites around Matijevic Hill and "move back and forth and up and down along the outcrop to really understand the structure and the stratigraphy and how the layers combined, and the composition and the variation in composition," Arvidson said.

and

"We will undoubtedly come back to Kirkwood, undoubtedly, and move along the length of the outcrop, looking for variations in the density and the patterns of the spherules and trying to find a big aerial exposure of the brecciated part of it, and trying to find a big aerial exposure of these veins so we can get the turret in there to do MIs and APXS' of these different parts of Kirkwood," said Arvidson.

Yes. And look how incredibly fine and cohesive the cuttings are from this APXS press. The impressions of the phillips-head screws are preserved. And note the fractures meandering across the smooth area.

An excellent anaglyph, but I also suspect that the left & right images are reversed. The Phillips head screw slots are indented. I was beginning to wonder if we had discovered buried metal machine parts!

The impression of the Phillips head screw slots looks correct in Bills non-anaglyph image. (link below)

Sorry guys - I'll make a better one next week when I'm back at work

Well they define it as sandstone (100u grain size). Those fines and the really fine clastic structure sure looks like mudstone and 100u is pretty much on the classification boundary. Maximum identified grain size? I wonder what the cementing is? Clay? It would be interesting to get Tim Demko's reassessment of this area now that we have more information available.

Ngunn - I really want to understand what you're saying, but this bit defeats me

Just noting that Cape York seems a continuation of the curve delineated by Cape Tribulation, Cape Byron etc. These are at the edge of the existing bowl and are raised well above the enroaching plains material. This effect would most likely reflect uplift rim.

Tiny bump downslope on 3092 - compare these two frames:
