#jezeroplaster — Public Fediverse posts

@65dBnoise @oldclumsy_nowmad the only peer-reviewed published I've seen is this one
https://mastodon.social/@sharponlooker/115252367928608221

but that only covers the crater floor, another one including even the delta is (was?) in the making
https://mastodon.social/@sharponlooker/113545747394238574

All covered by the #JezeroPlaster tag 😉

@oldclumsy_nowmad Glad you like them!

IIRC, desert varnish is what some geologists called it too in the beginning, but I think the process that creates it is different. Then there is what we #solarockers call #JezeroPlaster, which seems to be ubiquitous around Jezero Crater (images):

There was a paper that gave some explanation about the process, but I can't find it right now. Maybe @sharponlooker remembers?

@65dBnoise I haven't wanted to add the #JezeroPlaster tag to photos of this outcrop, not sure those are coatings.

@65dBnoise needs the #JezeroPlaster tag, they hit a speck of it with the laser too 😉

@jesusmargar most likely rock coating, imaged at close range during dusk/nighttime. For more examples: #JezeroPlaster

The final peer-reviewed version of the #JezeroPlaster paper, "only" for the crater floor campaign.

@65dBnoise I'm adding the #JezeroPlaster tag to this one, I guess coatings are ubiquitous around here, but there's a whiff of that "selective tainting" on some "tiles" there on the back as we saw on Hogwallow

New iteration on coatings from some of the same team that investigated the #JezeroPlaster

@65dBnoise Tagging the above post from sol 1294 with #JezeroPlaster

The paper above refs (2) a submitted one. Turns out it's still a preprint, waiting for peer review since 2023. I found the manuscript by chance while reading others, it's a whopping 500MB in that format!

Covers 3 categories of identified coatings on Máaz & Séítah, discusses potential origins & compares to previous coatings seen by other rovers.

#JezeroPlaster

Coating talk at last! "Plaster" gets its own category (Rockytop) and along with the Mn-bearing, is interpreted more as an infill, instead of airfall dust (purple aka "varnish")

@65dBnoise alright. If you remember, please use the #JezeroPlaster tag if you see more, so if the posts are public then we can search for them later on.

I played my "compatriot sedimentary geologist" card, and seeing the #JezeroPlaster as material seeping through cracks sounds very reasonable to me, specially after that supercam pic from yday @65dBnoise . See thread

@65dBnoise ikr? This is probably the same stuff that was visible with the "toaster" and the "toast"
