The main objective of the Geochronology and Geology Program is to characterize the temporal and spatial aspects of paleo-archaeological contexts, as well as their reconstruction and the study of their formation processes. This program straddles a wide spectrum of disciplines in the geosciences, such as geochemistry, geophysics, geomorphology, stratigraphy, mineralogy, petrology and sedimentology. The methods for reaching these objectives are often intrinsically bound up with the major instrumentation capacities. The special nature of chronostratigraphy and the dating methods render parallel advances in instrumental development and implementation, and the applications of the methods, necessary. To this end, the program dedicates significant effort to methodological advances, updating processes, and improving protocols to keep the laboratories in the forefront of research.
