UCLA Cosmochemistry Database
Extraterrestrial materials include meteorite falls and finds, micrometeorites, and interplanetary dust particles as well as samples returned from manned and robotic spacecraft. Samples have been retrieved from the Moon, several asteroids, a comet, and the solar wind. These materials provide otherwise unobtainable information about the chemical composition, formation, history, and evolution of the Solar System.
Since the 1960s, John Wasson, Paul Warren, and their UCLA colleagues have been analyzing the chemical compositions of a wide range of extraterrestrial materials including iron meteorites, stony iron meteorites, chondrites, achondrites and lunar samples. A large quantity of cosmochemical data has accumulated.
These comprehensive data can help in the recognition of new meteorite groups, the identification of grouplets, and the determination of possible pairing among discrete samples. These data form the basis for modeling the disparate formational processes in the solar nebula and for enhancing our understanding of the formation and evolutionary history of the Moon, asteroids, and planets.
