  • Tectonic Influences on the Spatial and Temporal Evolution of the Walker Lane: an Incipient Transform Fault Along the Evolving Pacific – North American Plate Boundary

    Tectonic Influences on the Spatial and Temporal Evolution of the Walker Lane: an Incipient Transform Fault Along the Evolving Pacific – North American Plate Boundary

    Arizona Geological Society Digest 22 2008 Tectonic influences on the spatial and temporal evolution of the Walker Lane: An incipient transform fault along the evolving Pacific – North American plate boundary James E. Faulds and Christopher D. Henry Nevada Bureau of Mines and Geology, University of Nevada, Reno, Nevada, 89557, USA ABSTRACT Since ~30 Ma, western North America has been evolving from an Andean type mar- gin to a dextral transform boundary. Transform growth has been marked by retreat of magmatic arcs, gravitational collapse of orogenic highlands, and periodic inland steps of the San Andreas fault system. In the western Great Basin, a system of dextral faults, known as the Walker Lane (WL) in the north and eastern California shear zone (ECSZ) in the south, currently accommodates ~20% of the Pacific – North America dextral motion. In contrast to the continuous 1100-km-long San Andreas system, discontinuous dextral faults with relatively short lengths (<10-250 km) characterize the WL-ECSZ. Cumulative dextral displacement across the WL-ECSZ generally decreases northward from ≥60 km in southern and east-central California, to ~25 km in northwest Nevada, to negligible in northeast California. GPS geodetic strain rates average ~10 mm/yr across the WL-ECSZ in the western Great Basin but are much less in the eastern WL near Las Vegas (<2 mm/ yr) and along the northwest terminus in northeast California (~2.5 mm/yr). The spatial and temporal evolution of the WL-ECSZ is closely linked to major plate boundary events along the San Andreas fault system. For example, the early Miocene elimination of microplates along the southern California coast, southward steps in the Rivera triple junction at 19-16 Ma and 13 Ma, and an increase in relative plate motions ~12 Ma collectively induced the first major episode of deformation in the WL-ECSZ, which began ~13 Ma along the N60°W-trending Las Vegas Valley shear zone.

The journal was patterned after the journal Radiocarbon and covered isotopic age-dating (except carbon-14) on rocks and minerals from the Western Hemisphere. Initially, the geographic scope of papers was restricted to the western half of the United States, but was later expanded.

It has occupied a criti- cal structural position in the western Cordillera since Mesozoic time. In the Cretaceous through early Tertiary, it stood just east and north of major fold and thrust belts and also marked the northern end of a broad, gently (~15o) north-plunging uplift (Kingman arch) that extended southeastward through much of central Arizona. Mesozoic and Paleozoic strata were stripped from the arch by northeast-flowing streams. Peraluminous 65 to 73 Ma granites were emplaced at depths of at least 10 km and exposed in the core of the arch by earliest Miocene time. Calc-alkaline magmatism swept northward through the northern Colorado River extensional corridor during early to middle Miocene time, beginning at ~22 Ma in the south and ~12 Ma in the north.

    CENTER FOR VOLCANIC AND TECrONIC STUDIES1 DEPARTMENT OF GEOSCIENCE University of Nevada, Las Vegas Las Vegas Nevidi.89154 Report No. 56 ANNUAL REPORT for the Period 10/1/90 to 9/30/91 Submitted to the Nudlear Waste Project Office State of Nevada December 14, 1991 'Eugene L Smith-Principal hvestigator. Daniel Feuerbach-Research Associate Terry aaumann-Research Associate 0 9210020232 911231 PDR WASTE WM-11 PDR INTRODUCION The annual report of the Center for Volcanic and Tectonic Studies (CVTS) contains a series of papers, maps, reprints and theses that review the progress made by the CVF`S between October 1, 1990 and September 30, 1991. During this period CVIS staff focused on several topics that had direct relevance to volcanic hazards related to the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. These topics included: (1) The role of the mantle in controlling the location and composition of Pliocene- Holocene volcanism. (2) The nature of boundaries between compositionally different mantle domains. These domain boundaries may control the location of surface faults and volcanism. (3) The detailed geology of the Pliocene volcanic cones in Crater Flat (4) The detailed geology of bedrock to the east of Crater Flat on Yucca Mountain. (5) The structural controls and emplacement mechansims of Pliocene/Quaternary basaltic volcanic centers and dikes. (6) The study of young felsic volcanism in the southern Basin and Range. (7) Estimating the probability of disruption of the proposed repository by volcanic eruption (this topic is being studied by Dr. C Ho-UNLV). Activities CV1S presented papers at several professional meetings including (a) The Geological Society of America Cordilleran Section Meeting in San Francisco- March 25-27, 1991.
