The Minnichhof meteorite

The dominant minerals of the Minnichhof meteorite are olivine (Fa25.3) and hypersthene (Fa2i.6) with nickel-iron (kamacite, taenite, plessite), plagioclase (An12), diopside of minor quantity and accessory chromite, merrillite, ilmenite, daubréelite and limonite. Specific gravity: 3.53. On the basis...

Description
Summary:The dominant minerals of the Minnichhof meteorite are olivine (Fa25.3) and hypersthene (Fa2i.6) with nickel-iron (kamacite, taenite, plessite), plagioclase (An12), diopside of minor quantity and accessory chromite, merrillite, ilmenite, daubréelite and limonite. Specific gravity: 3.53. On the basis of the given electron-probe microanalysis as well as the complete chemical analysis, X-ray diffractometric diagrams, spectrographical and mineral-petrographical examinations the stone is an olivine-hypersthene chondrite [MASON, 1962 and 1965], equilibrated, ordinary chondrite [DODD—VAN SCHMUS—WOOD, 1967] which belongs to the L-group [UREY—CRAIG, 1953] and can be classed into the L5—L6 types [VAN SCHMUS—WOOD, 1967].
