Winonaite Meteorite Classification

Class Description

A “Winonaite” is a type of meteorite that belongs to the winonaite group. These meteorites are classified as primitive achondrites, meaning they have lost their chondritic texture due to heating and partial melting but still have a composition similar to chondrites. Winonaites are equigranular rocks that may contain relict chondrules and have mineralogy and composition similar to chondrites, but they are more reduced in nature compared to H chondrites and are related to silicate inclusions found in IAB complex irons.
