    Going through my rocks from fieldtrips with a rocksaw, rediscovered this chunk of felsic sill with a twist. Shearing, or something more..?

    Drop by and chat about ignimbrite welding at , where I am presently presenting a poster on our work ! (or with @not_on_twiter_rachel, who is presenting her Masters work on the magmatism of Dunedin, NZ!)

    First poster presentation on our soon-to-be-concluded investigation of ignimbrite welding. I am incredibly lucky to have worked with et al on this short but amazing project. Looking forward to round 2 at VMSG 2020.

    Finished chucking electrons at a couple ignimbrite sections, now to make some borderline sense out of ‘em.

    The first chunks of data from MER ignimbrites has emerged from ImageJ, with significantly different vesicle morphologies, a potential clue to their emplacement & welding histories. w/

    Welded ignimbrite, paleosol, and an encore of columnar jointing, Tenerife. -Seeing ignimbrites in the field before upcoming project on MER specimen was incredibly humbling.

    Finale field day of El Hierro team, completing all 601 sample sites (although No.601 was sampled two days ago). A great experience with Laura from INVOCAN and “El” the flux meter. Ready to regroup with the Tenerife team.
