Hi Bernd and all. This pic of the day prompted me to take a look at my NWA
2624 slice again. Stunning meteorite!

Does anyone know if any other Ureilites have been found with pyroxene
megacrysts like this?

Cheers,

Jeff

Hello John, Anne and List,

Beautiful thin section picture! Gorgeous colors! NWA 2651 is
described as being similar to NWA 2624, which I can definitely
confirm. When the Hup?s offered this ureilite with its large and
translucent pigeonite grains, I found them so fascinating that I
decided to buy three slices (3 + 3.8 + 4 grams) and I am glad I
did!

Of course, after receiving my slices, I immediately put one of these
under my microscope and took a photo of the large, limpid gem-like
pigeonites at 16x magnification and was surprised when I detected
what is described as "olivine is highly fractured with closely spaced,
subparallel fractures".

These subparallel, grayish "stripes" are easily recognizable and even
those "saw-tooth" grain edges are readily visible at 16x.


Best wishes,

Bernd
