Meteorites

Brachinite

Early in 2019, a master 2 student, Neil Meunier-Mili, worked on a series of 12 brachinite meteorites. He studied the microstructures of these meteorites linked to plastic deformation in order to determine which processes participated in parent’s body formation. He obtained a PhD grant to continu this project, which is co-supervised by M. Bystricky and myself.

EETA 79001

This project is a collaboration between 3 institutions (Prof. A. Bouvier, Toronto, Prof. F. Jourdan – Curtin University Australia) to investigate the petrology, microstructure, chemistry and chronology of this sample obtained from the NASA.

EETA79001 is Martian shergottite (achondrite) and is very interesting because it contains two different lithologies.

Sandie during the field camp in Sardignia

In Lausanne, I study the petrology and the microstructure of the two lithologies and the relationship between them. During the spirng semester in 2016 a Bachelor student, Sandie Pasche, performed a detailed petrology of the sample and she was interested by the “melted zones” as melt pockets and melted shear-zones.
