“…ago and has continued, perhaps episodically, throughout the late Cenozoic (Ekren and Byers, 1984;Hardyman and Oldow, 1991;Dilles and Gans, 1995). Historic strike-slip rupture is recorded locally (Slemmons et al, 1979). In the Death Valley area, strike-slip movement is 14 Ma or younger in age, and locally some strike-slip faults exhibit Quaternary movement (Brogan et al, 1991).…”

“…In the Great Basin region of western Nevada and eastern California, this zone is the Walker Lane belt (Stewart, 1988(Stewart, , 1992aOldow, 1992), which is characterized by northwest-striking right-lateral faults and northeaststriking left-lateral faults. The oldest dated movement on these strike-slip faults is about 24 to 22 Ma (Ekren and Byers, 1984;Hardyman and Oldow, 1991;Dilles and Gans, 1995), and the youngest is historic (Gianella and Callaghan, 1934;Slemmons et al, 1979). In the Mojave Desert region, the strike-slip faulting forms the Eastern California shear zone, characterized by northwest-striking right-lateral faults and east-or northeast-striking left-lateral faults (Dokka, 1983;Travis, 1990a, 1990b;Dokka et al, 1991).…”

The Basin and Range province covers a large region of western North America and contains diverse late Cenozoic extensional structures, including metamorphic core complexes, detachment faults, strike-slip faults, and basin and range fault blocks. The central region of the Basin and Range province, extending from the northern Rocky Mountains in the western United States to Sonora, Mexico, contains local or regional areas characterized by moderate-to large-magnitude extension overprinted by basin and range faults that have produced major elongate mountain horsts or tilted blocks and intervening valleys underlain by grabens, half grabens, or downtilted blocks. In southeast Oregon and most the Mexican part of the Basin and Range province east of the Sierra Madre Occidental, the province is only slightly or moderately extended, and structures consist mainly of basin and range blocks produced by widely spaced high-angle normal faults. Strike-slip faults are most common in the western part of the Basin and Range province in the Walker Lane belt of Nevada and California, the Eastern Mojave shear zone of the Mojave Desert region, and parts of the Gulf of California region.Tilt domains in which the dip of stratified rocks and the tilt of mountains blocks are consistently, or fairly consistently, in one direction are characteristic of the Basin and Range province. These domains are commonly 50-200 km or more across in a direction perpendicular to the strike of stratified rocks and the trend of elongate mountain ranges and as much as 1,000 km across parallel to this direction. Tiltdomain boundaries (accommodation zones) consist of either (1) anticlinal boundaries where the strike of stratified rock and the trend of structural fault blocks is parallel to, and the dips or tilts are away from, the boundary; (2) synclinal boundaries where the strike of stratified rock and the trend of structural fault blocks is parallel to, and the dips or tilts are toward, the boundary; or (3) transverse boundaries at a high angle to the strike of stratified rocks and structural fault blocks. These transverse boundaries (transverse accommodation zones) mark areas across which the strike direction of Tertiary rocks and of mountain ranges remains essentially the same, but the dip or tilt direction reverses. Tilt-domain boundaries (accommodation zones) may correspond to areas of abrupt change in dip directions at individual faults or folds, or may be broad areas of structural change that are several kilometers to 20 km across.

“…The Walker Lane belt (Figure 1) is bounded on the northeast by the Walker Lane itself (a narrow linear zone passing near Fallon and Gabbs) and on the southwest by the Sierra Nevada front (roughly defined by a line trending N30°W through Lake Tahoe). Deformation in the Walker Lane belt between 39° and 40°N has been described in consecutive papers by Slemmons et al [1979], Bell and Slemmons [1979], and Sanders and Slemmons [1979]. The CNSZ [ Caskey et al , 1996] is defined by the ruptures associated with the 1915 Pleasant Valley, 1954 Rainbow Mountain‐Fairview Peak‐Dixie Valley, and the 1932 Cedar Mountain earthquakes, all magnitude ∼7 events [ Goter et al , 1994].…”

[1] The positions of 44 GPS monuments in an array extending from the Sierra Nevada at the latitude of Reno to near Austin, Nevada, have been measured several times in the 1993 -2000 interval. The western half of the array spans the Walker Lane belt, whereas the eastern half spans the central Nevada seismic zone (CNSZ). The principal strain rates in the Walker Lane belt are 29.6 ± 5.3 nstrain yr À1 N88.4°E ± 5.4°and À12.8 ± 6.0 nanostrain yr À1 N01.6°W ± 5.4°, extension reckoned positive, and the clockwise (as seen from above the Earth) rotation rate about a vertical axis is 13.6 ± 4.0 nrad yr À1 . The quoted uncertainties are standard deviations. The motion in the Walker Lane belt can then be represented by a zone striking N35°W subject to 16.8 ± 4.9 nstrain yr À1 extension perpendicular to it and 19.5 ± 4.0 nstrain yr À1 right-lateral, simple shear across it. The N35°W strike of the zone is the same as the direction of the local tangent to the small circle drawn about the Pacific-North America pole of rotation. The principal strain rates for the CNSZ are 46.2 ± 11.0 nstrain yr À1 N49.9°W ± 6.0°and À13.6 ± 6.1 nstrain yr À1 N40.1°E ± 6.0°, and the clockwise rotation rate about a vertical axis is 20.3 ± 6.3 nrad yr À1 . The motion across the CNSZ can then be represented by a zone striking N12°E subject to 32.6 ± 11.0 nstrain yr À1 extension perpendicular to it and 25.1 ± 6.3 nstrain yr À1 right-lateral, simple shear across it. The N12°E strike of the zone is similar to the strikes of the faults (Rainbow Mountain, Fairview Peak, and Dixie Valley) within it.

“…The study area for the current investigation is shown in Figure 1 and lies within the WLZ and adjacent regions of the western Basin and Range and includes sites along the Sierra Nevada frontal fault zone on the west and the north trending Nevada Seismic Belt on the east [e.g., Slemmons et al, 1979;Stewart, 1988Stewart, , 1992 as follows: an older phase characterized by NE to ENE trending extension directions (believed to correspond to a regionally defined "pre-basin-range" extensional phase [Zoback et al, 1981]) and a younger deformational phase corresponding with WNW trending "modern" basin-range extension [Zoback and Zoback, 1980Zoback, , 1989Stock et al, 1985;Zoback, 1989]. This .--40 ø clockwise change in the o3 stress direction was previously recognized elsewhere in the Northern Basin and Range province and is believed to have occurred between 10 and 7 m.y.B.P.…”
