MILLBILLILLIE

26*27'S., 120*22'E.

Wiluna district, Western Australia

Achondrite, Eucrite (Ca-rich)

Fell on October 1960 at about 1 pm. No specimens were recovered until 1970. This is a calcium-rich meteorite, thus producing a shiny black fusion crust. Many well-preserved, oriented specimens have been found by local Aboriginies. Millbillillie is a basalt that was rapidly cooled by extrusion to the surface of its parent body, possibly the asteroid 4Vesta. It is composed of roughly equal amounts of the plagioclase anorthite and the pyroxene pigeonite.
