Electron Microprobe is (among other things) a more quantitative way of
determining mineral composition that the traditional optical mineralogy
methods, so to understand Fayalite you should look into basic mineralogy
info. Fayalite is a component of Olivine, but separating out earth & ET
rocks depends on more than just one mineral. It seems the Fe/Mn ratio of
pyroxene is more commonly referenced. See for example "Pigeonholing
Planetary Meteorites" in the publications section of this website:

More on the differences between earth and space rocks can be figured out by
reading this article:

http://www.lpi.usra.edu/science/treiman/frass_rock.pdf

More on the mineralogy of meteorites can be found in many places, but this
one is tops:

Look through the old bulletins here:

Pick a couple good key words and more articles than you can read in a year
are here:

Best of luck on your rocks!
