The abraded surface in a combination of sol 257 images with SHERLOC Autofocus and Context Imager for detail and SHERLOC WATSON camera for enhanced color.
Do I see concentric zoning and lamellae in some crystals (I do not mean the visible effect of the abrading tool hammering), or are these just image artifacts or imagination ?

[Bill Harris]

We do see zoning as well as lamellae in these mineral grains. I'm thinking that the zonation is due to weathering in a wet and oxygenated environment. These rocks are covered with a weathering crust and this abraded area is just beneath that zone.

Sol 256 SuperCam Remote Micro Imager with Mastcam-Z context and anaglyph

[Bill Harris]

Percy hasn't covered much distance since leaving the Artuby ridge. But the Micro Imager shows consistent grain size, sorting, and angularity in several images. More important than the linear surface distance is the stratigraphic interval, which covers time as well as space. We don't know the deposition rates yet, so this time interval could be years, tens, or hundreds or thousands.

[Phil Stooke]

Since this is Mars, it could be hundreds of millions of years.

Sol 248 Mastcam-Z. Kodiak with enhanced colors and as anaglyph.
The stereoscopic effect is quite weak because of the large distances.
The visible distant part of Séítah is about 1 km away, Kodiak 2 km, and the inner crater wall about 7 km and more.

Latest sample from Jezero imaged in the rover's coring bit.
November 15, 2021 (Sol 262)
Edit: Added L-Navcam of the hole
Edit#2: roughly assembled raw 4-tile L-Navcam (MS-ICE)
All jpg'ed to reduce server impact

My take on the 4-tile NavCam Left mosaic.

[PaulH51]

Sol 262 CacheCam shows the core is in at least two sections. The 2nd (later) image provides us a with a side-on view of the upper section of the core closest to the camera.

I'm assuming the upper section of the core rotated after the static probe was used at the Volume station to measure the size of the sample, and to ensure there was room to fit the seal.

I'm sure geologists will enjoy this bonus side-on view of the split core and its grain structure.

Thanks a lot Tau for this superb work of yours

It took me a while to find appropriate context images.
