The Mills, New Mexico, Chondrite — A New Find

Abstract

A mineralogical and chemical analysis has been performed on a slice of the Mills, New Mexico, chondrite, which was found in August 1970. The mineralogical composition is olivine Fa19.S. bronzite, FS 17 .4> plagioclase, nickel-iron, troilite and ilmenite. The chemical analysis confirms that Mills is a typical bronzite, H5 chondrite, with considerable degree of weathering, as indicated by the presence of large amounts of Fe2030 A comparison with other stones found in the same New Mexico region by Nininger may show a possible relation between Mills and previous finds.
