Descriptive note by the author: "A type-II porphyritic pyroxene (PP) chondrule in crossed polarized light. Thin section from the NWA 4769 LL3.8, S1, W1 chondrite."
Hello List, An almost identical chondrule is pictured in: NORTON O. R. (2002) The Cambridge Encyclopedia of Meteorites (Cambridge University Press) on page 110. On pp. 109-110, you'll also find information on why this chondrule-type is called a type II porphyritic chondrule. Best wishes from the proud owner of a beautiful 5.95-gram slice of this troilite-rich desert beauty. My slice also features a gorgeous 7 x 5 mm troilite bleb and several oval chondrules!
