Here's my take on a bayer reconstruction of one of today's (sol 1100) releases. There's a lot of green in the image but that might be an artifact of the gimp and g'mic image processing although why it would produce those greens here might be a good question. If I were a Curiosity driver I would do some more checking into the green areas. But of course they will be ignored as usual.

There seems to be quite a lot of veins, damp appearing areas and "bayer greens" areas in the location Curi is now examining.

Sol 1100 enhanced difference false color Bayer panorama of rock outcrops in the Murray Formation area in Gale crater:

with location link.

Winston, the "Bayer greens" are likely JPG / Bayer processing artifacts.

I wonder why this area was singled out for the lossless Mastcam treatment? Why not just use the Chemcam for maximum resolution? Perhaps there is some interest in the color?

Anyway, the dogs barked and the caravan moved on.

Sol 1101 colorized Chemcam view of rock ledge in the Murray Formation area in Gale crater:

with location link.

Perhaps looking for a sheltered, accessible area to look for organics in the soil?

Here's an Xeyed 3D of a chem cam image from sol 1103. I haven't found the context image so far. But the Chem cam 3D sure looks interesting. Magnification is by 1.5.

I think this is where it came from. Very Interesting

Hort;

I think Curi has found the clays and a lot more.

LWS, here is the context image for your #1006: http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=1103MR0048880000601026E01_DXXX&s=1103

Thanks Paul;

I just found it also.
Its getting more interesting. My 1007 image was a festoon with with very interesting surface textures.

Here's my 3D xeyed of the sol 1003 context image for the pale blob of earlier Chem cam images.

The blob is on the surface of the dark foreground rock, suggesting clearly that it was recently laid down, paler outine areas suggest that the process may still be going on.

I wonder What it is!

Here's a crop of the fuzzy surface of the festoon imaged on sol 1105 by MAHLI imager.

Looks a little different to previous ones we've seen

Barsoomer, re your 1005, Thanks for posting that JPL release. Yes, that's the first I've heard that some of the sediments at Gale are being interpreted as ancient sand dunes. So the theories are evolving along the same lines as at Meridiani, where at first everything looked like water deposited layering, but over the months an aeolian explanation gradually became the primary one.

Does anyone have growing doubt that its all too good to be true, this spectacularly obvious layering almost everywhere we look? Now at Gale they're seeing at least two kinds of underwater deposit plus dunes, all in a small area and all eroded to museum quality visibility. This scene a sedimentologist's DREAM.

Curved layering is very rare at Gale, though its common in deposits created by water currents and by wind:

Here's a very important one from this morning's releases

Looks a lot like microbialite pinnacles to me. Could be even alive and currently growing

Curi is now in an area that seems to be replete with living microbialites. Hope it studies here well!

LWS, on your 1015:

That's exciting indeed. Hopefully Curi will camp here a bit.

Mini berries with stems? Also note the fine "twiggy" thing at the bottom.

Today and the past few days, several images were taken, of what I can only describe as "Growing" features - either growing via some sort of geologic/salt/chemical process, or "grew" some time ago and now eroded remains being exhumed. Or...potentially "growing" biologically mixed in with the soil forming the nodules...growing "up and out" of the sand and rocks.
