Résumé : | This initiation to research thesis aims to improve the scientific knowledge of the geology of the Vernet-la-Varenne region located in Auvergne in France, but also to provide details as the conditions of formation of the drusic amethyst in order to qualify geographic areas with potential for amethyst. After reminder of the geological history of Auvergne, this thesis presents the study of field data collected in the Vernet-la-Varenne area by providing more precision to the geological map of the region. A comparative study with geology of the Thunder Bay region in Ontario in Canada was also carried out to provide details on the formation of the drusic amethyst. Finally, a reinterpretation of radar data details the different stages, from data processing to their interpretation. All the results allow us to understand the complex geology of the Vernet-la-Varenne region and the contextualization of the drusic amethyst in the world. |
