[meteorite-list] what is the world standards for petrographical preparations(polarization microscopy)

[E. L. Jones]

I am also interested in the use of "quartz" as index markers.  This 
isn't in any of my reference books.  Are they attached to the specimen 
and ground at the same time as the thin section?

Another question I have.  Is there a house that specializes in 
preparation? Kinda of like the $2 a carat faceting deals one can get in 
Thailand?
