The meteorite Ural: New mineralogical data

New data on the mineral composition of the meteorite Ural found out near the village of Ural (Kurgan Region) in 1981 were obtained. It was established that the meteorite is composed of olivine (chrysolite), orthopyroxene (bronzite), clinopyroxene (diopside), plagioclase (albite), chromite, metals ir...

Description
Summary:New data on the mineral composition of the meteorite Ural found out near the village of Ural (Kurgan Region) in 1981 were obtained. It was established that the meteorite is composed of olivine (chrysolite), orthopyroxene (bronzite), clinopyroxene (diopside), plagioclase (albite), chromite, metals iron and nickel compounds (kamacite and taenite), sulfides (troilite and pentlandite), chlorapatite, and merrillite. Minerals such as diopside, taenite, pentlandite, chlorapatite, and merrilite were identified for the first time in the meteorite Ural. This work presents the chemical compositions of all minerals studied. The meteorite Ural is normal H5–H6 chondrite which is characterized by strong secondary changes both inside and outside, viz., development of a supergene mineral—goethite.
