Chondrites – Stony non-metallic meteorites which have not been modified by melting or differentiated of their parent body and contain chondrules. They were created by the accretion of dust and small grains present in the early solor system. Chondrites are one of the oldest materials in our solar system. Thus, they are believed to be one of the building blocks of the planetary system.

Chondrules – Round grains found in chondrites that form as molten or partially molten droplets in outer space before being accreted into asteroids. Chondrules are chiefly composed of the silicate mineral olivine and pyroxene. They are usually surrounded by glassy or crystalline feldspathic material.
