Geochronology: An Essential Pillar of the Geosciences — tribute to Jean David

Geochronology is a fundamental discipline in the geosciences, yet it is often undervalued. Since the 1990s, however, the work of Jean David, a geochronologist at the MNRF, has significantly enhanced our understanding of the lithostratigraphy of Quebec’s territory and has provided temporal constraints on major metalliferous events. To honour the invaluable contributions of Jean’s work, the presentations in this session will highlight the many applications of geochronology, drawing on examples from both Quebec and elsewhere. We will come to realize that geochronology is far more than a tool for calculating ages – it is a powerful means of deepening our understanding of Earth’s tectonic evolution.
