A very interesting closeup of a rock next to #Perseverance, showing some intriguing curved stripes. Millimeter scale.

More stripes and dark spots under close examination with artificial light at night by #Perseverance's WATSON instrument. The 3rd img is a composite with both day and night illumination.

@JoseAC
No, not false color, the first two are illuminated by artificial light at night. The third is a composition/mix of 2 images captured under artificial and natural light, which brings up details from both of them, so rather kind like a super-reality. Both WATSON's and MCZ's colors are close to what we'd be seeing on Earth.
How those colors would be perceived in reality on Mars by a human, what *impression* they would make, is yet to be determined 🙂
@65dBnoise are we sure it's not supercam showing weird artifacts? I know it's not your processing, because it's in the original. There's more subtle ones, but the one circled here doesn't look "natural"
[EDIT]: Ok, I now saw another view and your feature is still there, would be weird to get the same artifact there too, intriguing! https://mars.nasa.gov/mars2020/multimedia/raw-images/LRF_1798_0826554356_264EBY_N0870000SCAM02798_0100I6J
@sharponlooker
No, the one I focus on is real. That's what the pseudo 3D above shows, two different images of the same feature.
Hopefully this feature along with the black spots inside the abrasion will be a good reason for the #Perseverance team to write a new post.
Here's a new view of those black spots:

@tsrono
IIRC, we've seen some vaguely similar to those stripes features ("similar" as judged by my brain's pattern recognition neural system, which is of course biased toward earthly patterns) but they were of a much larger size.
Dark spots like those… I don't recall seeing before. Maybe @sharponlooker or @PaulHammond51 recall seeing something similar?
@65dBnoise if similar ones were seen at varying sizes that might be something of a clue for what could've caused them of course.
looking at it now, someone else in your comments mentioned the rectangle on the center left there - also i'm thinking that might be the same thing at the top right? could be mistaken of course but does hint at the 'stripe' pattern there.
@65dBnoise aye yeah, i'm not over here trying to do science. i'm just blabbering.
@65dBnoise @tsrono @PaulHammond51 IANAG™, but I suspect the dark spots are more olivine, just in a different mix , considering this is probably an older, less altered rock that those seen previously.
The stripes are something I haven't seen at that scale, they are so tiny... But someone with good knowledge of igneous processes and differentiation would probably diagnose them immediately.
