Description

Hello up for sale is the very famous Norton County meteorite classified as a Achondrite Aubrite. This gorgeous piece weighs 40.270 grams, its a McKinley stone. The iron content is so low that this meteorite fluoresces under a blacklight (see my last two photos) Aubrites are so reduced that they contain minerals not found, or rare, on Earth. It has a extremely fresh look, broken off a 35 gram piece I purchased on eBay originally from UNM. This meteorite fell on 02/18/1948 in Kansas USA, very rare type 1 of 65 ever approved. Thanks for your interest and take care. ASU says: Norton Countyis a rare type of meteorite called anaubrite, which is an enstatite achondrite.

This mineral is white inNorton County, as opposed to the more normal green to brown, because it contains so little iron in fact the iron content is so low that this meteorite fluoresces under a blacklight (see my last two photos) Aubrites are so reduced that they contain minerals not found, or rare, on Earth, including : Caswellsilverite NaCrS2 Daubrelite FeCr2S4 Oldhamite CaS Perryite (Ni,Fe)5(Si,P)2 Schreibersite (Fe,Ni)3P Spectral studies link the aubrites to a few near-Earth Apollo asteroids, specifically 3103 Eger and 434 Hungaria. Further spectral work is consistent with asteroid 3103 Eger as the source of the aubrites.
