V MartínNature´s microscopic art in Jezero's Earth analogue 😍

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:

Time to rethink what the mineralogy was saying about the #JezeroMarginUnit ? Radar sounding by RIMFAX finds deep traces of earlier deltas and rejects the igneous intrusive hypothesis. The plot thickens...

Hard to catch up with all the science when papers for 2 years of #PerseveranceRover campaigns (upper delta, margin unit and #NeretvaVallis / #JezeroBrightAngel) all get released within a few weeks 🤦♂️

Referenced in the above paper, had escaped me due to a different journal. Another detailed description of, imho, the most complex part of #PerseveranceRover traverse.

All the "gory" details on the Jezero margin unit 😉
Jones et al: "Stratigraphy of Carbonate-Bearing Rocks at the Margin of Jezero Crater: Evidence for Shoreline Processes?"
https://doi.org/10.1029/2025JE009111
There's also a reference to a new paper on the margin unit, with an excellent sketch of its proposed formation and alteration.

The greenish spots at the southern bank of Neretva are also astrobiology-interesting. #LeopardSpots #ReddestRock #MalgosaCrest #JezeroDeltaScience
