Polished section of a L6 chondrite with a metallographic
microscope with polarizer and analyzer. The polarizer and analyzer are slightly
uncrossed so that opaque minerals appear grey-blue instead of black.
Polished section of L6 Chondrite with the analyzer removed.
The white mineral is metallic iron, the bright slightly yellow is troilite (iron
sulfide) and the light gray can be goethite. The dark gray regions
are the transparent minerals.
