TL;DR: in situ carbonation of olivine is the preferred formation method for the #JezeroCrater carbonates detected by #PerseveranceRover along its trek.

#AtokoPoint and other Mount Washburn rock observations behind a paywall 🤦♂️ One can at least access the supplementary materials and this short film:

All the "gory" details on the Jezero margin unit 😉

There's also a reference to a new paper on the margin unit, with an excellent sketch of its proposed formation and alteration.

The kind of comparison with Eberswalde I've been waiting for...

More on the high-silica rocks story, with references again to AEGIS_0910A (https://mastodon.social/@sharponlooker/112073687379681538). The whole paper is quotable, so I just hand-picked some extracts from the discussion. This is the first time I see them referring to Turquino and surroundings as a "suspected inverted fracture

There's a few new #JezeroDeltaScience talks & posters at #AGU24, but only abstracts available in the schedule that I could find. Here's a couple covering Bright Angel, Mount Washburn & #AtokoPoint , you can find related ones at the bottom of each.

Preliminary presentation in #EPSC2024 of a paper on more modeling of Jezero water budget and delta timescales. Many constraints apply 😉
