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.

Peña Blanca Spring Meteorite Thin Section

On March 1, 2018 Roving Reporter’s pictures of the Peña Blanca Spring meteorite appeared on the Meteorite Picture of the Day website. I was immediately struck by this Aubrite’s sharp gray/white matrix coloration and its numerous inclusions. It is an exquisite meteorite! That weekend I decided that the next meteorite thin section to photograph will be the Peña Blanca Spring Aubrite. Presented here is the result of that decision: a large thin section in cross polarized light displaying the internal structure of this beautiful enstatite achondrite. The story of this meteorite’s discovery makes for good reading, so please enjoy: Story by John T. Lonsdale.

Dhofar 125 Meteorite Thin Section

Dhofar 125 has the smallest mineral grains of known acapulcoites. The Meteorite Studies link below gives additional interesting facts, such as the fact that the acapulcoites have elemental ratio compositions identical to that of chondrites. It is also known that all acapulcoites have a narrow cosmic ray age of 4 – 7 million years, perhaps indicating a common ejection event from the parent object. Some acapulcoites contain relic chondrules — in this thin section of Dhofar 125 you can see what I think may be relic chondrules.
