Mica Group
New Mexico Highway 1 roadcut, Sierra County, New Mexico, USA
Tiny, thin blades of a mica group mineral, exact ID not known, found on material I collected at the locality on November 7, 2014 with Jerry Cone. Possible species are biotite, phlogopite or muscovite based on visual observation. I only have two small samples so far; if I find more, I'll sacrifice one to analysis. Comments are welcome!
