“…Originally mapped as Furnace Group, the San Bernardino carbonate strata may actually range from Cambrian to Permian in age (Brown, 1984). As such, this sequence is stratigraphically equivalent to portions of the classical section exposed in the Grand Canyon (Stone et al, 1983). Marbles in the San Bernardino Mountains experienced contact metamorphism during Mesozoic-aged granite emplacement and are now preserved as roof pendants along the mountain front, which has been tectonically active since the late Pliocene.…”

“…The shoreline could not be located with any degree of confidence in the southern part of the Arizona-California area. The area shown as land, however, includes areas reported to contain Coconino Sandstone or the metamorphosed equivalent, the Coconino Quartzite (Stone et al, 1983). Shorelines farther east in Arizona, New Mexico, and west Texas are based on studies by McKee et al (1967), Rascoe and Baars (1972), Blakey (1980), Handford and Fredericks (1980), and Kottlowski (1985).…”

“…Latest Precambrian-early Paleozoic cratonal and transitional miogeoclinal-cratonal strata are found regionally in the Providence and Marble Mountains and ranges in their vicinity (Fig. 1) (Hazzard, 1954;Stewart, 1970;Stone et al, 1983), in the Death Valley area (Wright et al, 1974; not shown in Fig. 1), and in scattered exposures south, west, and northeast of Alvord Mountain (Stewart and Poole, 1975;Boettcher and Walker, 1993;Martin and Walker, 1995;Schermer et al, 2001; Fig.…”

The pre-Cenozoic geology of Alvord Mountain, located in the central Mojave Desert of California, records a complex history of deformation, magmatism, and metamorphism related to development of the southern North American Cordilleran arc. Paleozoic schist and marble are the main preintrusive rocks. The rocks are correlated with either lower Paleozoic displaced eugeoclinal rocks that are part of the Antler allochthon and/or with uppermost Permian(?)-Lower Triassic continental-borderland rocks. These rocks were intruded by a monzodiorite to quartz monzonite pluton (mainly quartz monzodiorite) during the early Middle Jurassic. Both the metamorphic rocks and the quartz monzodiorite pluton were subsequently metamorphosed, folded during northeast-southwest contraction, and sheared along northwest-striking, steeply dipping shear zones. The timing of deformation is bracketed between 179 Ma (the age of the quartz monzodiorite) and an undeformed 149 Ma gabbro. Both the prekinematic and postkinematic plutons are parts of larger regionally recognized suites of Jurassic plutonic rocks. Northwest-striking hornblende diabase dikes are correlated with the 148 Ma gabbro and are interpreted to belong to the regional Late Jurassic Independence dike swarm. Metapsammites in the schist record conditions of upper-greenschist-lower-amphibolite facies, but the age of metamorphism is uncertain. Peak metamorphic conditions were probably attained during Jurassic time closely associated with intrusion of the main Jurassic quartz monzodiorite. However, petrographic observations and 40 Ar/ 39 Ar data from biotite from the 179 Ma pluton indicate that Late Cretaceous plutons and dikes (ca. 85 Ma), which crop out in the southern part of the range, probably produced a static thermal overprint. Northweststriking Late Cretaceous granodiorite porphyry dikes crop out for several kilometers along strike and approach thicknesses of 10 m. The dikes cut all pre-Tertiary rocks and correlate with a newly recognized Late Cretaceous dike swarm that is oriented roughly parallel to the Late Jurassic Independence dike swarm. The style and timing of deformation at Alvord Mountain are similar to those seen in the nearby Cronese Hills and Tiefort Mountains, where structures have been correlated with the Jurassic-Cretaceous East Sierran thrust system. Unlike the reversesense, mostly downdip shear zones in the Cronese Hills and Tiefort Mountains, smallscale shear zones at Alvord Mountain primarily show evidence of strike slip. A Miller, J.S.
