20997-184 - NWA Iron Meteorite. In study. 210g Pecopteris North Korea (3)Petrographic description Under polarized light microscope, any minerals were identified. The sample is totally composed of opaque minerals (ore minerals, metals). The scanning electron microscopy reveals that the chemical composition of the sample is mostly homogenous native iron (Fig. 2). Some areas are more altered, with formation of iron oxide minerals (hematite magnetite). Silicate minerals are also observed as plagioclase and Fe mellilite (Figs.
