Ah, the LJ app arsed that up to a fare-thee-well. Fixed now!
(Though I somehow think that taking photos down the eyepiece with a phone camera may not be the best way to illustrate the wonders of the petrological microscope :) )
Do you have the S276 mineral identification cheat sheet?
...now you're scaring me :)
Awww, sorry. But do come back and see if you'd still say that* after your weekend learning rocks ;-).
*Biotite's one of the easy ones (in thin section and in hand specimen). Garnet's pretty easy to find too.
Then if you're in the field in Scotland, you spend ages going "are there any higher grade minerals" and unless there's a tutor there, decide everything is a garnet-mica schist ;-).
(Which is not to imply that that looks like a garnet-mica schist. It's a bit hard to tell what it IS based on that one shot, without being able to rotate it or switch back and forth between x-polarised and plain polarised light)

Fortunately I was intending to spend the weekend learning to recognise rocks anyway...
