Most of the Cosmochemistry Group’s research concerns
the meteorites known as chondrites.
Unlike the meteorites from the Moon or Mars, these are almost
certainly asteroid fragments and they have escaped the processing that comes
from being part of a major planet.
Their composition, textures, and ages show them to be the oldest
materials in the solar system. They
are witnesses to the nebula from which the Earth and planets formed.
