Some late-breaking discussion on the Ireson Hill caprocks from LPSC last week: these appear to be a new class ('Pogy') of basaltic sediment found within Gale Crater. They're unusual in that they're alkalic, but look like they have a different source region from similar rocks (e.g. Jake M) that have been studied previously. The Pogy rocks have a low potassium and nickel content, but are heavily enriched in calcium. So far these don't look like they were a major contribution to the Murray sedimentary system (if they even belong to it), and might represent a brief pulse of activity from another sediment source. Pogy-class rocks also have Fe/Mg ratio and CaO/Al2O3 ratios, which is similar to shergottites. That's about all I understood from the talks.

Cool! Was this a ChemCam talk?

It's a mix of information from ChemCam (John Bridges) and APXS/basalt chemistry modelling (Mariek Schmidt) talks.
