A 3D X-eyed take on some new sol 1526 releases.

This is possibly the most biological looking image I've seen from Curi. It has putative spores, filaments, dark matrix and everything else. It is somewhat reminiscent of the sol 312 MH images. Hope they'll do some MH images of this area.

View the image at 200% magnification using stereophotoimager. Lots of stuff to see there.

Context images are on my Smugmug photosite.

The "context" 3D for the above image

Here's another 3D. From sol 1529 this time.

I think it shows the "terrace type veins" as layers reminiscent of the microbial mat crusts in earth's stromatolites. The image may well be a serendipitous one in that the context image shows the mudstone, veins and crusts that are all typical of stromatolites. It also suggests that much of the action is from the dark matrix of the "soil"

Examine the 3D at 200% in stereoimagemaker.

The Veins / crusts are clearer to see in this 3D of the middle section of the rock, which I think is a stromatolite.

There will be an AGU press conference next week on Dec. 13 about new Curiosity rover results, and new paper, reportedly about "reduced organic compounds" according to some tweets.

Here's a colouration of one of today's chem cam releases. This colouration shows some structures that are very reminiscent of fungal mycelium on Earth. They are also the first time I've seen such structures with green colouration intimately associated with veins.

Hoping that we'll get some MAHLI closeups of these rocks and any other similar ones in the area in the near future.

Indeed, some of the objects remind me of arthropods feeding on fungal spores but that is just wild speculation. Looking forward to some MAHLI closeups to set the record straight.

Here's an X-eyed 3D that I think shows the component parts of a martian stromatolite from sols 1544 and 1545.

Here's the context image for the above 3D's.

It was a montage made from four sol 1545 ML images. The 3D was made cropped from the central portion of the montage combined with an MR of the relevant rocks.

Nice images, Winston. What IS the material between the rocks that appears semi-transparent where it is shallow and seems to have a greenish cast where it is deep.

Barsoomer;

Here's another Chem cam colouration. From sol 1546 this time. The mudstone inclusions on and near the veins look interesting as does the green coloured blobs.

Re. your question about the "sand" on which the rocks float. I don't know the official chemical characterization of the sand. Bt I think it is a sandy matrix of eroded material from nearby as well as distant rocks liberally coated with salts such as perchlorate and sulphates as well as with putative microbial content which largely provides the chemical reactions and the generally greenish oliveaceous colours. THis material appears to surround most rocks in Gale crater.

The blobs remind me of this:

gypsum layers

Barsoomer;

Hort did a colouration of a homestake MI (Oppy) which was even more reminiscent of the gypsum veins in your reply 94 above.

Barsoomer;

THis what I've been trying to get posters on this forum to see since Curi landed.

Thanks, Winston. The AGU Fall meeting in San Francisco is currently in progress and there seem to be a bunch of interesting abstracts there. One might almost say revolutionary.

Manganese (Mn), suggesting possible higher past atmospheric oxygen levels.

Boron, potentially related to RNA and the origin of life---borates found in veins.

Also more evidence from Curiosity that organics are widespread on Mars, but not mentioned at AGU briefing on Tuesday.

Plus the organic macromolecules which have been found...
