Sayh al Uhaymir 001 was a huge find, well over 400 kg. Steve Brittenham’s recent post on Paul Swartz’s Meteorite Picture of the Day induced me to check out a couple thin sections I had made some years back. The meteorite is “only” an L5 and has suffered shock, thermal metamorphism and terrestrial weathering, but it still retains interesting features.
The samples are small and not covered.
Barred olivine chondrule. Field of view, FOV, is 2 mm wide. Plane polarized light, PPL.
The same barred olivine chondrule. FOV = 2 mm. Cross-polarized light, XPL.
Barred chondrule fragment. FOV = 2 mm PPL.
The same barred chondrule fragment. FOV = 2 mm XPL.
A wedge shape portion of a chondrule in XPL.
The rest of that chondrule with the crossed polarizing filters having been rotated.
One millimeter diameter chondrule with dust rim and shattered grains. XPL.
Portion of a large POP chondrule. FOV = 5.3 mm XPL.
Rust stained layered barred chondrule at the edge of the sample. ~1.3 mm diameter. PPL.
Same 1.3 mm diameter layered chondrule. The glass slide appears black in XPL.
Incident light reveals two or more layers of metal and sulfide blebs.
Small chondrule with several sets of fine bars, colorful in XPL. FOV = 0.6 mm.
