First analysis of the #JezeroRimSpherules by the aptly-called " #PerseveranceRover Crater Rim spherule beds analysis team" in a recent #EGU26 abstract. It favours the impact spherules scenario but doesn't rule out volcanic origin.

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.

Poster on #FreyaCastle / "zebra rock". Not sure if we can see which one is #KautzCreek without the #PDSAnalystNotebook perhaps.
