Determining the timing of geologic events is essential for elucidating both Earth history and for understanding rates of Earth processes. Researchers at UM use both thermochronology (U-Th/He methods) and geochronology (U-Pb methods) to undertake absolute dating of geologic materials in order to deepen our understanding of tectonic, petrologic, climatic and biologic processes.
