L type ordinary chondrites are the second most common group of meteorites, accounting for approximately 35% of all those cataloged, and 40% of the ordinary chondrites. The name comes from their relatively low iron abundance, w/respect to the H chondrites, which are about 20–25% iron by weight. Historically, L chondrites have been named hypersthene chondrites or olivine hypersthene chondrites (as w/this specimen) for the dominant minerals, but these terms are now obsolete. Many of the L chondrite meteorites may have their origin in the Ordovician meteor event. Compared to other chondrites, a large proportion of the L chondrites have been heavily shocked, meaning that the parent body was catastrophically disrupted by a large impact. This event has been radioisotope dated to roughly 470 million years ago. The parent body/bodies for this group are not known, but plausible suggestions include the 433 Eros and 8 Flora asteroids, or the Flora family as a whole. Offered here is a 1-7/8x6-1/8x1/8" thick slice of a L chondrite meteorite that weighs 125.03 grams and has had one side polished to a smooth finish, revealing the meteorites high nickel-iron content. This meteorite fell near Carnegie in Caddo County, OK and was first discovered in 1963. Aside from two cut sides of slice, specimen edges are covered w/a fusion crust which covered the entirety of the meteorite due to the immense heat generated by entry into the atmosphere. 1.75" long edge does not have fusion crust edge as this part broke off upon impact. Slice shows impact fracture line running through slice, though it remains stable. Wonderful display, allowing for viewing meteorite's mineral make-up. From the Robert M. Overstreet Collection and comes with COA.
