Description

A chondrite is a type of stony meteorite that contains chondrules, small spheres of molten rock formed in the early Solar System. They are the most common stony meteorites and are considered some of the oldest rocks in the Solar System, formed about 4.5 billion years ago.
Main characteristics of chondrites:
Chondrules:
The distinctive feature of chondrites is their chondrules, small spheres of molten silicate that cooled rapidly in space.
Composition:
Chondrites are composed primarily of silicates, metallic iron-nickel, and sulfides, and have a composition similar to the original solar nebula.
Undifferentiated:
Unlike other types of meteorites, chondrites have not undergone differentiation (density sorting) or melting, making them valuable sources of information about the early Solar System
