Figure 1. Generalized map displaying radial, downdip distribution of kinematic indicators on Mormon Peak detachment. Outcrops of detachment hanging wall are shaded. Only faults that cut detachment are shown. Constrained structure contours link two mapped outcrops of detachment. Inset equal-area projection shows difference between detachment striae (dots) and previously published S75°W extension direction. Geology south of Mormon Peak is generalized from Wernicke et al. (1985).

(A) Geologic cross section C–C′ across the Mormon Mountains showing the geometries of the Mormon Peak detachment (MPD) and Tule Springs detachment (TSD). Cross section is oriented approximately parallel to the slip direction of the faults. Thermochronology samples, shown as red dots, are projected into the plane of the cross section. In this projected view, samples may be above or below topography of the section line. Mean zircon and apatite (U-Th)/He ages (Ma) and errors (1σ standard deviation) are shown above each sample. Cross-section location is shown in Figure 2. Units and symbols as in Figure 2. St Dev—standard deviation. (B) Restored-state cross section shows the initial dips of the detachments and the preextensional configuration of our thermochronology samples. Cross sections are modified from Axen et al. (1990). (C) Mean zircon and apatite (U-Th) He ages versus distance from the Tertiary unconformity. Error bars are 1σ standard deviations. Cross sections are modified from Axen et al. (1990).

Map of the same area in Figure 2A showing locations of the Sevier ramp syncline (white line), thrust truncation of the top of Mississippian strata in the footwall (pink line), and the ramp anticline (thick black line). The three lines in northwestern corner of the map are above the detachment; lines in the central and eastern part of the map are below the detachment. Lines are dotted where projected. Thin black lines show major post-detachment normal faults. Dashed lines show offsets of structural features along the Mormon Peak detachment slip direction. Inset shows a schematic cross-section of a thrust ramp, showing positions of the offset thrust ramp features. Colors: Olive, Proterozoic basement; browns, Cambrian–Ordovician; lavender and blues, Devonian–Permian; greens, Mesozoic; purples and orange, Tertiary; yellow, Quaternary.

 Figure 4. (A) Photograph of the Mormon Point detachment ∼300 m east of Badwater Road in the western Mormon Point study area (Fig. 2). The exposure is oriented roughly east-west parallel to the slip direction (white half-arrow) of the hanging wall relative to the footwall. The hanging wall above the principal slip plane (PSP), consisting of Quaternary fanglomerate, was displaced down-dip relative to the footwall after 770 ka. Most of the fault rocks below the principal slip plane are foliated breccia in zone II. Gray fragments of gravel from the hanging wall were mixed with brecciated orange and brown marble and gneiss derived from the footwall. The fragments of hanging-wall gravel are elongate and extended and define the oblique foliation dipping less steeply than the principal slip plane. Lenses exhibit pinch-and-swell structure, and one is cut by an R1 Riedel shear. (B) Photograph of the Gregory Peak detachment. The scale bar is 10 cm long. The sense-of-slip (white half-arrow) is top-to-the-right (west). Immediately below the principal slip plane (PSP) is a 10-cm-thick layer of gouge. Next below, zone II consists dominantly of reddish-brown foliated breccia mostly derived from sedimentary rocks in the hanging wall. A prominent Riedel shear is indicated by a dashed red line and labeled R1. It cuts across and offsets a lens-shaped fragment of fanglomerate preserving an oblique P- foliation indicated by dashed white lines. Smaller-scale Riedel shears cutting smaller foliated lenses are overlain by red dashed lines. Sense-of-slip on the Riedel shears is the same as that along the principal slip plane: top-to-the-west.
