The goal of this course is to become familiar with the good practices for the analysis of small geological objects of microscopic size. These objects, such as fluid, vitreous or mineral inclusions in minerals for example, are frequent in Earth Sciences and often carry rich and key information. On such small objects, analyzes shall be carried out in situ, before perhaps sacrificing them for a final analysis requiring extraction. The example of materials under extreme pressure and temperature conditions, mandatory to model the physico-chemical properties of the interior of the Earth and planets will also be discussed.<\/p>

The main techniques of in situ microanalysis, to gain chemical and physical information, will be presented \u2013 approximately 2 hours lecture, and then practically implemented when available in our partner laboratories \u2013 lab work of 3 to 4 hours. Otherwise, data available in the instructors' portfolio will be used. in situ <\/i>tant chimiques que structurales seront pr\u00e9sent\u00e9es – 2 h de cours environ, et mises en \u0153uvre lorsque celles-ci sont pr\u00e9sentes dans les laboratoires partenaires – TP de 3 \u00e0 4h. Dans le cas contraire, des donn\u00e9es disponibles dans le portfolio des enseignants seront utilis\u00e9es.<\/p>

Following each lab work, students write an experience report illustrating the relevance and limitations of the technique (personal work estimated at 4 hours\/topic).<\/p>

The class includes a visit to the ESRF (European Synchrotron Research Facility) in Grenoble to raise the awareness of students on the great potential of selected beamlines and more generally large international facilities.<\/span><\/p>
