today i purchased this really unusual Rock/Fossil/ tooth and i would love to know what it is.
it looks to be Organic the material flakes away fairly easy (kind of similar texture to horn), the out surface/enamel is shiny, and the overal touch of the piece is cold like stone. i brought it with some antique items this one is on an antique wooden base which some one has made for it, so i would think at some point it was possibly cherished by the owner.
it is a large piece is measures approx 10.25 cm tall. i would love to know anything about this even if its just guesswork.
thank you in advance,
kind regards steven
It is a (nice) piece of what I might call micaite - a rock composed predominantly of mica.
It seems to be a pale mica, the most common of which is muscovite - so that is the most likely in your case.
Micaite is a term I thought I had just invented, but it seems somebody else got there before me. Funny, but in all my years of geologizing, I can't remember having thought of a need for such a name, though it makes perfect sense now. Usually, one (as a geologist) thinks of mica as occuring in schists or pegmatites or, in smaller grains, in metamorphic or igneous rocks. Schists, especially, are often qualified in terms of their major component minerals, eg. garnet mica schist. A schist composed of almost 100% mica could be called a mica schist, for sure; but it could also, logically, be called a micaite.
Thank you so much for your quick and informative reply, this is my first post on this forum and i will definatley come back. many thanks steven
