EU 13: Meteorites & Solar System formation

This course’s objective is to present the most recent advances in the field of cosmochemistry, i.e. the study of meteorites. Meteorites are rocks fallen from the sky, originating from small bodies (asteroids and comets) and also from the Moon and Mars. Their laboratory study enables an understanding of the formation and evolution of our solar system.

Immense progress has been recently accomplished, in particular because of the comparison of astronomical observations of star-forming regions (Orion, Taurus) and laboratory data obtained on meteorites. We will more particularly address the following topics:

- Generalities on meteorites
- Basic extraterrestrial mineralogy
- Chondrites and protoplanetary discs
- Planetary differentiation
- Radioactive clocks and chronology

Most of the course will consist in plenary lectures. A 3 hours class will be devoted to meteorites observations with a suite of microscopes

The bulk of this course will consist in lectures at the Muséum National d’Histoire Naturelle, where the French national meteorite collection is curated. One 3-hour session will be devoted to microscopic observations of meteorites. A visit of the mass spectrometry laboratory will be organised.

Lecturers: M. Gounelle, E. Jacquet, M. Roskosz, S. Pont.
