Description
The Prescott area is within the Yavapai geologic province which consists of rocks of Paleoproterozoic age, with typical igneous-rock ages of ~1700 Ma. Three 7 ½' quadrangles in this area have been mapped under the Arizona STATEMAP program (Chino Valley North, Paulden, and Wineglass Ranch), three more are drafted but not yet released pending incorporation of geochronologic, geochemical, and other data (Jerome Canyon, Chino Valley South, and Prescott Valley North), and two more will be mapped in 2012 (Fig. 1; Sullivan Buttes, Prescott Valley South). Rocks mapped during these mapping projects were sampled for U-Pb geochronologic study. U-Pb geochronologic analyses of single zircon grains, reported here, were done by LA-ICP-MS at the Arizona Laserchron Center at the University of Arizona. LaserChron Center facilities support was provided by NSF-EAR 1032156. This is a brief overview of new U-Pb geochronologic studies associated with the recent STATEMAP mapping.
