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

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 🤦♂️

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.
