The seminar was given by Dr. Imene Kerraouch from the Institut für Planetologie, Universität Münster (Germany) and the Astromaterials Research and Exploration Science, NASA Johnson Space Center (USA).

The wide diversity of meteoritic materials collected indicates that there are numerous parent bodies in the solar system, which presumably have varying origins and undergo different evolutionary processes. However, the dynamics of meteorite delivery to Earth are selective. Therefore, it is assumed that the recovered meteorites are derived from about 100 parent bodies (including Mars and Earth's Moon). This necessitates the search for new materials to improve our understanding of the parent bodies that populate our solar system.

The work presented in this talk contributes to our current understanding of meteoritic diversity by examining unique clasts in brecciated meteorites that result from collisions between asteroids. Such clasts provide new rock types from both unsampled parent bodies and unsampled parts of known parent bodies. In that sense, brecciated fragments also offer opportunities to study impact processes on planetary bodies, their collisional evolution, and their structure.
