Melnikovo is a relatively unweathered 545.6-g LL6 chondrite that was found in 1983. Only a few poorly defined chondrules are discernable in the examined sections; two of these are enriched in chromite. The meteorite contains olivine (Fa(27.8)), low-Ca pyroxene (Fs(24.4)), plagioclase, rare clinopyroxene, chlorapatite, merrillite, and opaque minerals, which have a modal abundance (in wt pct) of troilite (3.9 pct), kamacite (0.4 pct), taenite plus tetrataenite (0.7 pct), chromite (0.8 pct), and trace amounts of ilmenite and Mn-ilmenite. The meteorite appears unbrecciated on a centimeter scale.
