Thanks, John. Could they be something like stromatolites in your opinion? Winston? I'm no expert in that. 😉 There are some raw ChemCam images, but not enhanced versions yet.

Paul,
Here are some close-ups. In some places the knobs look like they are on top of the rock, in other places they look like a part of the rock that may be subject to a slight change in mineralization. I wish we could get these colorized:

Thanks, John. Yes, I've seen lots of ones similar to reply #160. Some other interesting new closeup ones today also:

I'm curious about any analysis!

Hi John

I think your reply 162 images are unique ones of a new mars rock type. Again there seems to be some biology there.

I think I found the context image. Tomorrow I will try to colourize the chemcam image using it. In the meantime here's my autoequalized version of the sol 1718 context image.

Winston.

John;

Here's a colourization of the 1718 chemcam image from sol 1718 using the image in my reply 164 above.

Winston,
I don't know how you do that colorization but it is nice!
I have a bit of a dilemma with what we are looking at. These dark spots do look like they are in some way a part of the rocks they are on, either a chemical-mineralization change or some kind of mineral or biological growth. But there are also some similar looking dark... somethings in the area that are not attached to rocks:

Take a look at the lower right close-up below. A similar color but not attached to a rock:

I am thinking these are related but also different, the way an alien rover landing in a forest clearing on earth would send back images of green pine trees, green oak trees, green wild grass, etc.; different species of photosynthesising plants (not saying these are plants!)

John;

Here's my colourization of the second image in your reply 166.

Its the best I could do but is somewhat fuzzy.

The dark rocks resemble tafoni (somewhat related to stromatolites) and seem to be mostly emplaced over the dark fine grained matrix.

Thanks Barsoomer for sorting out the index page.

Hmm, planetary scientist Nathalie Cabrol has said these dark nodules look like lapilli to her. Thoughts?

Paul;

re. Nathalie Cabrol's suggestion re lapilli, She may be right but I wonder if she considered that the dark nodules, from the Mast cam MH images and the Chem cam images, appear to be actually covered by a dark crust.

I think the lapilli is a good suggestion but I am not 100% convinced. As I suggested in #166, I think the dark, loose material may be related but slightly different. Especially the flat pieces with the soft edges (lower middle of first image in #166 and lower right of the second). Similar color but very different and interesting shapes.

Here are some Images from Earth for comparison:

If it is lapilla, it adds to the evidence of more super volcanoes.

Intruiging MAHLI closeup of surfaces of some sol 1727 rocks.


Looks like some biology might be hanging around. Lots of variously coloured small specks and grains.

Here is one of those dark pieces that is not quite as rounded on the edge:

This light colored stuff does not look like a vein but is a bit different, especially with the bubble like piece to left of it, bottom middle. Also the context it is found in is unusually complex:

Interesting recurring curved lines in the top Left as well.

Here's a sol 1725 panorama of an interesting feature near Curi

debris flows exhibiting seeming plasticity from under surfaces indirectly disturbed by Curi wheels. Look at top and mid left side of image. Area exuding flows do not appear to have been directly disturbed by Curi.

Sol 1729 image has been cropped, auto equalized, colour enhanced and sharpened in Gimp.

The British popular press has picked up on this, attributing it to Curiosity. I would like to know what the NASA source, if any, is.

Winston, your reply 175 image is spectacular. Does this mean that Curi has finished crossing the "river" of dark sand and is now on the Mount Sharp side proper?

Paul;

The Coast to Coast image is from Curi sol 528.

It very strongly resembles a martian thrombolite (a type of stromatolite). See my book "The living rocks of Mars"
