Abstract
The PhD project titled ‘Nanoscale geochemistry and geochronology of xenotime: application to Earth sciences’ aims at identifying and understanding mineralogical mechanisms that impact geochronometers at the nanoscale. The project focuses on the nanoscale geochemical behaviour of xenotime and their implications in geochronology, using a multi-scale study approach. The thesis presents nanogeochronology method of xenotime dating using atom probe tomography and detailed case studies of xenotime from three different geological conditions.
