Rock crushing and thin section
Service information
The laboratory has facilities for preparing small chips, coarse and fine powders of rocks, minerals and/or artificial materials for mineral separation, X-ray diffractometry or bulk chemical analysis. Moreover, mineral separates may be obtained by magnetic separation.

Furthermore, in collaboration with the geologic thin section laboratory, the lab produces thin sections of natural and artificial lithoid materials and of incoherent or poorly consolidated materials after impregnation by epoxy resins. Thin sections may be prepared with different size, final thickness and finishing (highly polishing, staining, etc.) for various purposes (sedimentologic and biostratigraphic, mineralogic and textural studies, porosity characterization, scanning electron microscopy, electron microprobe analysis, laser ablation ICP mass spectrometry, etc).
The lab also supplies polished blocks and cross sections of plasters, mortars and pottery.
Separate rooms are dedicated to the various activities.
The laboratory provides support to teaching (undergraduate, post-graduate and PhD students and to research. We also undertake external work from clients worldwide.
