[QUOTE="user 23515, post: 668726, member: 23515"] Stills would be good next time. :) Too hard to see detail in the small bit and would like to see larger in still pics from each side. That said. Metamorphosed sedimentary rock. Looks like there is mica and is lined up on roughly the same plane (foliation from pressure on the original), would love to see it bashed with a hammer and see how it breaks and surface detail, how minerals line up. A metamorphosed Mudstone? Shouldn't really be that much mica in a quartzite as the original sandstone it formed from would have had to have quite a bit of clay (changed by heat into mica). TBH guessing with out being able to see a clearly photographed freshly broken surface close up and whole specimen. After all that, I will go with low grade schist. [/QUOTE]
