Summary:

zzzzzNamed for exposures in southwest part of quad. Type locality is on Crazy Basin Creek, T10N, R1E, Mayer quad, Yavapai Co, AZ in Southwestern Basin-and-Range region. Exposure in Mayer quad is the northern part of a large pluton that extends southward into Crown King and Bumblebee quads. Intrudes Spud Mountain Volcanics. Is younger than Badger Spring Granodiorite (new). Is a coarse-grained quartz monzonite with conspicuous pink microcline crystals associated with white plagioclase and quartz. Biotite is the chief accessory mineral. Of Precambrian age. [DENVER GNU]

Summary:

Assigned to suite four (of 4) in the Prescott area (Yavapai County, Arizona, Southwestern Basin-and-Range region). Suite four, consisting of syn- to post-tectonic, moderately to coarsely porphyritic, coarse-grained biotite granodiorite to granite plutons, includes the 1,700 +/-5 Ma Crazy Basin Quartz Monzonite, granite of Iron Springs, granodiorite of Yarnell, and granodiorite of Hozoni Ranch. All except Crazy Basin are metaluminous, have moderate to high magnetite concentrations, and high barium, rubidium, zirconium, lanthanum, and cerium. All except Crazy Basin are restricted to the northwestern part of the area. Age of Crazy Basin is refined from Proterozoic X to Early Proterozoic. Report includes geochemical analyses.
