I don't know much about this meteorite.  It was found in 1998 in Libya.  The thin section I used was from Ivan Koutyrev.
 
These images are taken in typical cross polarized transmitted (pass through) light combined with incident (reflected) light.  This process is TRICKY!  Getting the correct balance is often elusive.  It is hard enough to bring together everything required to get a nice shot in either method.  When you combine the two, one always wants to over power the other.  To much or to little light and you loose detail and or contrast.
 
Experimentation is the key.  Make your light sources adjustable.  If one is a non adjustable lamp such as a vapor bulb (mercury, xenon, etc) then find some way to adjust light input.  The last photograph is a home made aperture I used in taking these micrographs.  Not much to look at, but it worked!
