The following information is about Chondrite.
Chondrite Defined
An abundant class of stony meteorites with chemical compositions similar to that of the Sun and characterized by the presence of chondrules (see definition below). Chondrites come from asteroids that did not melt when formed and are designated as H, L, LL, E, or C depending on chemical compositions. The H, L, and LL types are called ordinary chondrites. The L chondrites are composed of silicate minerals (mostly olivine and pyroxene, but feldspar as well), metallic nickel-iron, and iron sulfide (called troilite). Most L chondrites are severely shocked-damaged, probably by a large impact on the asteroid in which they formed. The C (or carbonaceous) chondrites are the most primitive meteorites. They contain water-bearing minerals and carbon compounds including a variety of organic molecules such as amino acids.
This definition is in context to Planetary Science. See more contextual defintions for Chondrite.
