Vermillion is an ungrouped pallasite that was found by farmers in Marshall County, Kansas, while planting a field. Although the 34.36 kg meteorite was discovered in 1991, it was not recognized as a pallasite until 1995.

Vermillion is an unusual pallasite in that it contains 86 volume % FeNi-metal and 14 vol.% silicate minerals, including approximately 13% olivine and 0.7% pyroxene.

Uncommon specimens, such as Vermillion, may help scientists better constrain the processes governing the formation of pallasite meteorites, as well as their provenance.
