Gallery Quick Links
This gallery shows an NWA 6393 Howardite meteorite thin section viewed in cross polarized light.  I often use retardation filters to draw out more color and control contrast. The Met Society write up on this material can be found at this link. I have to say, Howardites are very interesting on a microscope!

I start with a zoom series from the whole thin section to 760X.
This set is taken in a magnification of 160X.
