Three Iron meteorites, namely Sikhote Alin, Campo-del-Cielo, unknown and one stony meteorite Chelyabinsk, were investigated to study their elemental composition, oxide composition and physical parameters in detail and to confirm their originality. XRF analysis carried out for Iron meteorites showed that they contain above 90% Fe and Ni above 4% with other elements in minor quantities and stony meteorite major component showed SiO₂, and Fe₂O₃, with other components in minor quantities. The physical parameters carried out, the images of meteorites in the figures and analysis through XRF, showed that the samples under study are meteorites in origin. This paper reports the work carried out to study the meteorites and their physical properties, and to put on record their elemental composition, their physical properties and through this work to confirm their originality as meteorites on prima facial basis. A standardless approach has been adopted.
