Crustal Imaging and Characterization Team
Geochronology is the science that deals with measuring past time and assigns events to their proper dates based on geologic data. 40Ar/39Ar geochronology has evolved into one of the most commonly used isotopic dating techniques because of its applicability to a broad range of geologic problems. Currently, this method is applied to geologic studies on the origin and thermal histories of mineral deposits; emplacement, cooling, and uplift history of plutonic rocks; formation of metamorphic belts; development of volcanic terranes; formation and amalgamation of the Earth's crust; age and development of the landscape; and the timing of catastrophic events in earth history.
We welcome your interest in our world-class geochronology laboratory in Denver, Colorado.
