description Sioux County Overview
Sioux County is a eucrite meteorite that fell in Nebraska in 1933. Eucrites are basaltic achondrites formed from cooled magma on a differentiated parent body and belong to the howardite-eucrite-diogenite, or HED, meteorite association. Sioux County has been used as comparative material in laboratory studies of basaltic meteorites and of the geological processes associated with asteroid 4 Vesta.
help Sioux County FAQ
What type of meteorite is Sioux County?
Sioux County is a eucrite, a type of basaltic achondrite that formed from cooled magma on a differentiated parent body. It belongs to the howardite-eucrite-diogenite (HED) meteorite association, a group linked by shared geochemistry.
Where and when did Sioux County fall?
Sioux County fell in Nebraska in 1933, giving the meteorite its name. The circumstances of its recovery made it a well-documented American eucrite fall.
What parent body do HED meteorites like Sioux County come from?
HED meteorites are widely believed to originate from the asteroid Vesta, one of the largest objects in the main asteroid belt. This connection is supported by spectral data from NASA's Dawn spacecraft, which orbited Vesta and found surface composition matching HED meteorites.
Has Sioux County been used in scientific research?
Yes. As a well-documented eucrite fall, Sioux County has served as comparative reference material in studies of differentiated meteorites and the geological history of Vesta. Its availability in research collections has made it useful for analyzing basaltic processes on asteroids.
