Brief description Rates of metamorphic processes - correlating U-Pb ages with the pressure-temperature conditions of mineral growth. To determine the speed of metamorphic processes, the age obtained from accessory uranium-bearing minerals will be correlated to pressure and temperature obtained from major rock forming minerals. I will develop a new and innovative technique that uses trace element geochemistry to provide this link. The trace element partitioning between datable minerals (zircon, monazite and titanite) and key metamorphic minerals will be investigated in natural samples and in piston cylinder experiments. I will apply this technique to the study of processes such as the exhumation of eclogites in subduction zones and the duration of granulite-facies metamorphism in lower crustal rocks.
