Pre-Yavapai orogeny tectonic model for eastern Mojave province. A, Eastward subduction of oceanic lithosphere forms arc in the Ivanpah-New York Mountains area of eastern California between 1.76 and 1.74 Ma. The Yavapai arc is also active at this time (Karlstrom and Bowring 1993). Slab rollback results in the formation of a back-arc basin in the Arizona Mojave subprovince. Partial melting of the asthenosphere initiates basaltic magmatism. Introduction of heat by the basalt causes partial melting of the eastern Mojave crust and consequent rhyolitic magmatism forming bimodal supracrustal rocks. Quartz-rich detritus is derived from the eastern California arc and possibly the Bagdad block. The mixing of juvenile basaltic material and eastern Mojave crust results in the formation of the isotopically mixed Mojave-Yavapai boundary zone. B, Arc migrates east into western Arizona (former site of the back-arc basin) due to shallowing of the subducting slab resulting from the increased convergence rate, the introduction of anomalously thick oceanic crust into the subduction zone, or both. The eastern California arc shuts off. C, Due to increased coupling along the subduction zone, the Yavapai arc impinges on the easternmost Mojave province resulting in D1 deformation, M1 metamorphism, and tectonic burial to 20–25 km. The basin closes by thrust faulting. Speculatively, the Yavapai arc basement (oceanic lithosphere) is detached on impingement of the Yavapai arc with the eastern Mojave province. Continued collision results in crustal overthickening, inception of middle to lower crustal melting, and gravitational collapse sometime before the ca. 1.70 Yavapai orogeny (not shown), as proposed by Bonamici (2007) and Bonamici and Duebendorfer (2009).

Relative probability and cumulative number diagrams for data shown in Figure 4. Timing of Mazatzal and Yavapai orogenies is after Whitmeyer and Karlstrom (2007). Note that zircon crystallization ages in northern New Mexico display a single broad peak, consistent with the Yavapai orogeny. Oldest garnet age peak is interpreted as onset of prograde amphibolite-facies metamorphism. Oldest hornblende age peak is interpreted as onset of cooling from metamorphic peak in high-grade metamorphic rocks of the Cimarron Range, with later protracted cooling across the rest of the terrain. Oldest biotite and muscovite ages are interpreted to mark the end of high-grade metamorphism during the Picuris orogeny. Isotopic dates younger than the oldest muscovite and biotite cooling ages are interpreted to indicate tectonic reactivation and protracted slow cooling in the middle crust (Grambling and Dallmeyer, 1993; Karlstrom et al., 1997; Shaw et al., 2005).

Figure 10. Accretion of Yavapai arcs was closely followed by voluminous intrusion of granitoids (dark green; ca. 1.72–1.68 Ga) that stitched existing province boundaries and helped to stabilize juvenile crust. Distinctive quartzite-rhyolite successions (stippled yellow) occurred during the Yavapai orogeny (ca. 1.70 Ga). Pinal and Lower Manzano Group arcs (light blue) are outboard of Yavapai southern convergent margin. S.L.T.Z.—Spirit Lake tectonic zone.

Tectonic model for quartzite deposition and deformation in the Yavapai Province, southwestern United States. Basin development, quartzite sedimentation, and widespread rhyolitic volcanism (and contemporaneous granitic magmatism) are interpreted to have occurred in the upper plate of a north-dipping subduction zone during an interval of slab rollback following the ca. 1.70 Ga culmination of the Yavapai orogeny. Basin closure and quartzite burial and deformation occurred during the Mazatzal orogeny. CB—Cheyenne Belt. Figure was modified from Figure 3 of Giles et al. (2002) (also after Magnani et al., 2004; Selverstone et al., 1999; Karlstrom et al., 2005).

Schematic tectonic models for the southwestern USA approximately following the N–S transect of Shaw et al. (2005). (A) Mountain building and contemporaneous basin development and magmatism during the Yavapai orogeny at ca. 1705 Ma, modified from Jones et al. (2009) and Holland et al. (2020). (B) Model for the Picuris orogeny involving more localized deformation nearer the Cheyenne Belt and more regional tectono-metamorphism to the south. Widespread ferroan magmatism is interpreted to be associated with the underplating of basaltic, tholeiitic magmas (Gonzales et al., 1996; Frost and Frost, 1997; Frost et al., 2001). Adapted from Shaw et al. (2005), Karlstrom et al. (2016), and Holland et al. (2020); see references for additional details.
