— Sychevka is a relatively unweathered 65‐kg iron meteorite that was found in Russia in 1988. The microstructure, mineralogy and bulk composition of Sychevka as revealed by optical microscopy, electron microprobe and instrumental neutron activation analysis indicate that this meteorite is a group‐IIIAB medium octahedrite. Sychevka consists of (in vol%): kamacite (82.5), plessite (16), schreibersite (1.5), and rare grains of chromite and troilite.
