[Rockhounds] New Mica

[Pmodreski at aol.com]

I was going to write and comment, that it's considered very "bad form"  
scientifically for any one to use or even disclose a proposed new mineral name, 
 before it has been officially approved and published.
 
However, I looked this up on mindat.com and read,
 
"A dark green brittle mica. An intermediate between "xanthophyllite" (=  
clintonite) and chloritoid. [Clark, 1993 - "Hey's Mineral Index"] 
Originally  described from Mavinhalli, Mysore, Karnataka, India."
 
So this is not a new species, the name has evidently been around at least  
since 1993, and it's probably best considered to be a varietal term or a  
mixture, unless someone does future work to clarify whether it  really could 
be a separate distinct mineral species.  I see that  the pictures of it 
posted on mindat show that it's attributed as being in the  green micaceous 
material that surrounds ruby in matrix from Mysore, India.

I don't  collect rare species, but this one came to me in a swap, and I 
thought  some of you might like to see it.
