SaU 562 Meteorite Thin Section

SaU 562 is an unbrecciated eucrite with “approximately equal proportions of anhedral to bladed, white plagioclase (to 3 mm) and honey-brown, anhedral, granular pyroxene (to 1.5 mm) crystals.”

Interesting story about this thin section. I originally thought it was an unclassified eucrite; the label reads “Labenne Eucrite” and I was told it was unclassified when the thin section was made around 2009. After some friendly help, I discovered it had been classified as SaU 562. I was surprised to find that it was a eucrite which I had already photographed! However, this previous SaU 562 post was one of my first attempts at making a panorama, so a comparison between the old and the new reveals my progression of tools and technique quite well.

NWA 5903 Meteorite Thin Section

This thin section image of NWA 5903 provides viewers with an abstract painting created by nature. To look at a thin section of any rock under cross polarized light is to view the emergent features of mineral formation. Sextillions upon sextillions of atoms all interacting! It is fascinating to observe how matter crystallizes in various geometries and how this crystallized matter acts under polarized radiation. The eucrites are always wonderful to view this natural process, and NWA 5903 does not disappoint. The calcic plagioclase and exsolved pyroxene are mostly what give this image its incredible beauty.

Ibitira Meteorite Thin Section

Thin section of the Ibitira Meteorite viewed in cross polarized light. The numerous vesicles distinguish this meteorite and it has been noted that Ibitira probably represents a sample from a distinct parent body, i.e. not 4 Vesta.

John Kashuba created a spectacular set of micro vision images of Ibitira at Meteorite Times. Read further scientific details at Meteorite Studies.
