... Mountains lie within the Mazatzal Province, which consists of mafic-felsic igneous basement of likely arc origin that is as old as 1.68 Ga in southern New Mexico ( Karlstrom and Bowring, 1988 ; Amato et al., 2008 ). The igneous rocks in the province range in age from 1.7 to 1.6 Ga, and most have juvenile...

As a result, three major Paleoproterozoic crustal provinces (Mojave, Yavapai, Mazatzal) were formed that now border the Archean craton on its southern flank ( Fig. 1...
