NWA 5426 Meteorite Thin Section

Cross polarized thin section specimen of NWA 5426. There are two really amazing chondrules you should try to find while viewing the panoramas. NWA 5426 is a R Type Chondrite; “R” symbolizing the type specimen found in Rumuruti, Kenya. According to Norton’s The Cambridge Encyclopedia of Meteorites, these R Type Chondrites are mostly brecciated. In the case of NWA 5426, it is a polymict breccia. Of all the chondrites, R Type Chondrites contain the highest levels of iron oxidation.

Abee Meteorite Thin Section

Abee Meteorite Thin Section

Abee Meteorite thin section specimen. The photos were taken under blue cross polarized light. Abee is an example of the enstatite chondrite class of meteorites. The E Type chondrites are know for their reduced state and contain very little oxidized iron. Instead the iron is either metallic or joined with sulfur. They are mostly composed of their namesake magnesium rich orthopyroxene silicate mineral, enstatite. For more information see page 115 in Norton’s The Cambridge Encyclopedia of Meteorites.
