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 Hupés 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 ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
