The late Miocene to Pliocene Silver Peak–Lone Mountain extensional complex in the western Great Basin is part of a structural stepover that links dextral transcurrent motion between the Furnace Creek fault system and northwest-striking transcurrent faults in the central Walker Lane. In the Silver Peak Range, the extensional complex is exposed as a west-northwest–trending turtleback structure that consists of a folded detachment fault separating a metamorphic lower-plate assemblage from unmetamorphosed upper-plate rocks. The upper plate preserves structurally attenuated lower Paleozoic carbonate and clastic rocks, upper Oligocene to lower Miocene volcanic rocks, and a synextensional mid-Miocene to Pliocene clastic and volcanic succession. The three-dimensional geometry of fault-bounded extensional basins formed during displacement on the detachment is preserved, and the synextensional units comprise five sequences separated by unconformities. The locus of deposition migrated spatially as dimensions of small basins changed through time. The entire extensional complex is deformed in two generations of late Cenozoic folds. North-northeast–trending folds formed first with axial traces oriented at a high-angle to upper-plate extension, and these are preferentially developed in proximity to thrusts and partially inverted extensional faults. Younger, west-northwest–trending folds parallel the axis of the turtleback structure and involve all lithologic units, several syndepositional high-angle faults, and the basal detachment. Pliocene growth of west-northwest–trending folds marked the end of slip on the exposed parts of the basal décollement and the cessation of deposition in the fault-bounded basins. Today, upper and lower plates of the extensional complex are dissected by north- to northeast-striking normal faults that cut alluvium and cross-cut and locally reactivate earlier Cenozoic structures.

Velocity vector diagram comparing short-term (decadal) geodetic deformation rates versus long-term (Pleistocene; 103–105 yrs) geologic fault slip rates across the northern eastern California shear zone from the footwall to the Lone Mountain fault, Nevada in the northeast to the Sierra Nevada, California in the southwest, USA (see line A-A’ in Fig. 3). Three vectors are plotted for dextral slip along the White Mountain fault zone (WMFZ): a minimum slip rate of 0.8 mm/yr (Kirby et al., 2006), a minimum slip rate of 1.9 mm/yr (Lifton, 2013), and predicted slip rate of ∼2.7 mm/yr from one of our kinematic models (see discussion in the text). The sum of the geologic fault slip rates is projected toward 323° (dashed lines), which is parallel to Sierra Nevada block relative to the central Great Basin (SN-CGB) motion. The GPS velocity of 10.6 ± 0.5 mm/yr is a model far field velocity of GPS vectors projected to line A-A’ (Fig. 3) (which is perpendicular to SN-CGB) and that takes into account interseismic strain (Lifton et al., 2013). Fault abbreviations not defined in Figures 2 or 3: CVF—Clayton Valley fault; EPF—Emigrant Peak fault; LMF—Lone Mountain fault; VT—Volcanic Tableland faults.

Map of the central and northern Walker Lane showing major fault zones and global positioning system (GPS) velocities (after Hammond and Thatcher, 2004; Table 1). Normal and dextral faults shown outside Lake Tahoe have deformation rates &gt;0.2 mm/a (USGS, 2005). Sinistral faults shown have deformation rates &lt;0.2 mm/a. The white on black GPS arrow to the west of Lake Tahoe shows a calculated relative velocity difference of 2.7 ± 0.9 mm/a between stations UU83 and A270, which are located to the north-northwest of Lake Tahoe and on the east side of the Carson Valley, respectively. At the eastern margin of Walker Lane, normal faults strike north-northeast and include the Central Nevada seismic belt. Dextral faults dominate away from the margin of the Sierra Nevada microplate and strike north-northwest. Sinistral faults strike northeast and are primarily located perpendicular to dextral faults in Northern Walker Lane.

The Putnam thrust has long been recognized as an important Mesozoic structure in the northern Portneuf Range, southeastern Idaho. At most localities, the thrust places Ordovician rocks above Permian and Pennsylvanian rocks, although near its southeastern extent, it ramps laterally downsection to the southeast. At its southeasternmost exposures, Cambrian rocks are juxtaposed above Mississippian rocks. New work indicates that the hanging wall of the Putnam thrust contains three imbricate thrust slices or subplates, which are, from structurally lowest to highest (and generally from north to south), the Lone Pine subplate, the Narrows subplate, and the Bear Canyon-Toponce subplate. The steeply south-dipping, east-trending Narrows thrust overlies the Lone Pine subplate, underlies the Narrows subplate, and is a lateral ramp that merges eastward into the Putnam thrust. Where exposed, the Narrows thrust places Late Proterozoic quartzite of the Brigham Group over Ordovician and Cambrian rocks. The Bear Canyon thrust overlies the Narrows subplate and underlies the Bear Canyon-Toponce subplate, dips eastward along the west side of the Portneuf Range, and places lower Brigham Group quartzite above Cambrian limestone and Cambrian and Late Proterozoic upper Brigham Group quartzite and argillite. At its northern extent, the Bear Canyon thrust curves to the east, where it merges with the Putnam thrust. On the east side of the range, the intensely folded Toponce thrust places upper Brigham Group quartzite above Ordovician rocks; the Toponce is believed to be an eastward extension of the Bear Canyon thrust. East-dipping rocks within the Lone Pine subplate were not strongly deformed during Cretaceous thrusting, in contrast to rocks within the Narrows subplate, where east-vergent recumbent folds, cleavage directions that fan about northerly strikes, and tectonic thickening and thinning of beds indicate intense, thrust-parallel shear. The deformation and thrust geometry within the Narrows subplate suggest that the Narrows subplate actually consists of several horses within a foreland-dipping duplex. Late Miocene and younger basin deposits occur in north-trending valleys adjacent t o the northern Portneuf Range and, to the west, the Bannock and Pocatello ranges. At most places, the Neogene deposits dip to the east by as much as 35°, indicating that late Miocene and younger extension and down-to-the-east rotation occurred along mostly west-dipping listric faults that are inferred to merge on at least one regional detachment. Although range-bounding faults account for a large component of extension and rotation, an additional large component was contributed by numerous, relatively small-displacement normal faults within mountain ranges.
