[1] The meteorite was found near and was named after Vermillion, Marshall County, Kansas.
[2] Vermillion meteorite consists of around 86 volume-% meteoric iron and 14 % silicate minerals.
[3] Other accessory minerals include troilite, whitlockite,[1] and cohenite.
[4] The Vermillion meteorite is classified as a pyroxene pallasite because it contains pyroxene as an accessory mineral and shares a distinct oxygen isotope signature with Yamato 8451.
[1] Some studies also object to this grouping, referring to the differences in siderophile trace elements and the occurrence of cohenite in the Vermillion meteorite.
