Hi Jim,
The electron microprobe is the workhorse for classifications, and most
of this can be done simply with a probe mount (epoxy mounted sample
that has been polished). In general you don't need a thin section or a
petrographic microscope, although I always use a reflected light
petrographic
I always want a doubly-polished thin section to do classification of stony
meteorites. To determine the petrologic type of a chondrite, it is useful
to gauge the degree of recrystallization (best done in transmitted light)
and look for the size of plagioclase grains (which can be done in an

Hello Melinda, Alan and Carl,
Thank you all very much for these explanations and the learning
opportunity. You folks are great! I suppose I over worry about things
when one person orders a mount and another a mount and thin section and
another just a thin section. Sometimes a returned
