THE NUCLEAR MICROPROBE USED TO INVESTIGATE METEORITES

During many years a growing group of researchers has been involved in the study of meteorites. Meteorites are the only objects originating f rom the solar system in its early stage and accessible to detailed res earch. Research on meteorites has been done with a wide variety of ana lytical techniques for the investigation of their chemical composition , structure and texture, presence of isotopic anomalies, radioactivity and so on. Since the development of the nuclear microprobe, this inst rument also has been and is used as a probe for the investigation of m eteorites. In this contribution, results of the ongoing research with the nuclear microprobe on meteorites is described.
