Case study example
Semi-quantitative chemical analysis of an altered limestone coming from a borehole drilled in the sixties on the Lascaux Hill
Local context of the study:
- Cécile Verdet PhD (2015 – 2018) (Thesis Dir.: Colette Siriex, Thesis Co-dir.: Yannick Anguy ), Université de Bordeaux ED SPI 209 (Contingent « soutien à l’interdisciplinarité »).
- Research collaboration between the GCE and TREFLE departments of I2M.
- Setting up of the research operation « Painted Caves » (C. Sirieix) transverse to I2M.
- Partner : DRAC Aquitaine.
To the left, chemical contrast image (backscattered electrons) of an altered limestone sample. To the right, mineralogical phases identified based on a semi-quantitative chemical cartography performed with an Energy Dispersive Spectrometer(EDS).
