Comments:The rock has a moderate petrofabric. Many of the low-Ca pyx phenocrysts in the chondrules exhibit polysynthetic twinning. There are some AOAs and some Fluffy Type A CAIs. Many chondrules have igneous rims around them. Chondrules are very sharp and have a mean size of ~900 µm. 5 stones weighing 414.53g were purchased at the Tucson show 2015. In April of 2015 while on expedition in Morocco, 2 more stones matching the 5 from Tucson weighing 389.71 grams were purchased in Morocco by Sean Tutorow and Dustin Dickens from eegooblago meteorites.; submitted by Sean Tutorow
