U-Pb zircon analyses indicate both emplacement at 21.0 ±0.5 Ma and significant Precambrian zircon inheritance. Dates on monazite are 17-19 Ma and are interpreted to have remained near their closure temperature of about 700 °C for several million years after emplacement, resulting in Pb loss by diffusion. We suggest that the granite was emplaced into rocks which were at high temperature and that they remained so until late Miocene northeast-tilting, rapid uplift and/or tectonic denudation, and cooling.
