Very cool!
Those larger "blue" rocks should definately be analyzed closer... -------------------- - Lars

With the context of the large stitched image, it's VERY interesting to a geologist. I can see both decimetre-scale crossbeds and centimetre-scale ripples (or wavy lamination, anyway). There are undulating beds on a variety of scales and quite a bit of sedimentological information.
As for the blue "peas" I see very few signs that they are in bedding-parallel layers, and repeated occurrences of lineations - like a row of dots. I think there are more of these than random chance would allow. And I agree that there are some interestingly large lumps of blue - big enough for Mossbauer and APDX? -------------------- - Nick

Nah, cancel the non-random bit. I ran a simulation and it looks like random chance is good at making lines of 4 dots. A bit like playing "constellations"? I'll post a pic if I can work out how...

Also, the loose ones would tend to congregate in cracks and troughs and form lines that way.
What's up with the apparently segregated patches of light blue and dark blue berries? Is that real or an artifact of the stitching? -------------------- |

It is an artifact of the stitching be due perhaps to A: different exposure levels for each channel of each section, and/or B: different light condictions.

Yup - blame the obscure filters and unpredictable exposures
 Couldnt match them better than that without them being terribleDoug |
