Find books B. die Whipple Mountain Detachment Fault. The low-angle Whipple Mountains detachment fault divides the crust into upper and lower plates. In order to interpret these seismic reflections and to understand why detachment faults are imaged on some profiles but not on others, we collected oriented rock specimens from all major structural units in the Whipple … The footwall was exhumed from below the brittle–ductile transition and has a ∼3.5 km thick mylonite zone with the same shear sense as the brittle slip on the detachment surface and that is … The mylonitic front is a gradational SW-dipping contact between Tertiary mylonitic gneisses and structurally higher, … In the Whipple Mountains, just the exposed portion of the detachment fault is more than 30 … Brecciated clasts within this zone have a matrix of chlorite, epidote, silica, and sulfide minerals, especially pyrite; the alteration and mineralization render … Chloritic breccias beneath the Whipple detachment fault (WDF) have much lower seismic impedance than that of rocks occurring both structurally above and below. 1), has an areal extent in excess of 10,000 km 2, involves a relative displacement of at least 40 km, and juxtaposes rock types with radically different geological histories (Davis & Lister 1988). ^ Davis GA. (1988). ↑ Davis, G.A. We conclude that a large rollover growth structure formed in the hanging wall of the Whipple detachment fault shortly prior to emplacement of the voluminous War Eagle landslide (megabreccia). I’m a Ph.D student working with Dr. Chloë Bonamici in the fields of metamorphic petrology and stable isotope geochemistry at the University of Wisconsin-Madison. ↑Haakon Fossen. The present-day landform of the Whipple Mountains is a series of sub-parallel ridges trending northwest to southeast, cut at right angles by a large wash, (Whipple Wash), which bisects the entire range.These linear ridges mark the tops of tilted crustal blocks lying in the hanging wall of an extensive detachment fault, and the range as a whole comprises one of the best exposed … OSTI.GOV Conference: Evidence for late movement on the Whipple detachment fault, southeastern California Photo by C.Roig.

Below the fault is a chlorite breccia zone, up to 400 feet thick, whose rocks have been altered, faulted, and brecciat ed. As first described by Greg Davis (circa, 1982) for the Whipple Mountains; a listric normal fault By contrast, LANF fault rocks exhumed from the mid-crustal brittle–plastic transition at temperatures of 250 to 420 °C, several LANFs (the Woodlark Basin detachment, Zuccalle Fault, and the Whipple Detachment) exhibit compelling field evidence for overpressure, such as fault-parallel tensile veins (Roller et al., 2001, Collettini et al., 2006, Selverstone et al., 2012) Tertiary sedimentation along the Lake Mead fault system, Virgin Mountains, Nevada-Arizona However, the significant thinning of the chloritic breccia zone to the southwest of the Whipple Mountains may have caused the poor image of the WDF on the CALCRUST profiles. Detachment Fault Model Detachment faulting is thought to have played an important role in the Tertiary evolution of the Sacramento Mountains, so it is necessary to expand upon a simple reference to the process. Geology, 1994. Il précise alors comment certaines épreuves ont été modifiées, d’autres ajoutées ou retirées. Crystalline rocks of the lower plate are exposed in the core of a complex dome, and are separated into two structural domains by the Whipple mylonitic front. Journal of Structural Geology, 14:1033–1046. Continued extensional evolution of the Whipple detachment fault caused tilting of the upper‐plate strata and the formation of numerous half and full grabens as well as roll‐over structures. 1988. A short summary of this paper. dipping Whipple detachment fault of southeastern California, and western Arizona, for example (Fig. Binet y explique que la version de 1908 a fait l’objet d’éloges autant que de critiques, citant notamment les travaux des Américains Henry H. Goddard (1866-1957) et Guy Montrose Whipple (1876-1941) et que certains points devaient donc être améliorés. Jane Selverstone. Oxygen isotope compositions of epidote and quartz from chloritic breccias that underlie the detachment fault in the metamorphic core complex of the Whipple Mountains yielded quartz-epidote fractionations that range from 4.1 to 6.4 per mil and increase systematically toward the fault. Rapid upward transport of mid-crustal mylonitic gneisses in the footwall of a Miocene detachment fault, Whipple Mountains, southeastern California. The Whipple detachment fault apparently developed within crystalline rocks, but in some places now separates upper-plate Tertiary sedimentary and volcanic rocks from lower-plate cryste.lline rocks. en The latter is underlain by blind reverse faults probably merging into a detachment fault … PDF. The footwall of this fault exhibits a range of mid-crustal rocks deformed near the brittle-ductile transition, including mylonites, cataclasites, and pseudotachylites, which provide insight into mid-crustal … Whipple detachment fault).

The role of extensional tectonics in the Caledonides of South Norway. 1992. Oxygen isotope compositions of epidote and quartz from chloritic breccias that underlie the detachment fault in the metamorphic core complex of the Whipple Mountains yielded quartz-epidote fractionations that range from 4.1 to 6.4 per mil and increase systematically toward the fault. The Whipple detachment fault (WDF) is a low-angle normal fault (LANF) that accommodated 40–50 km of top-NE extension from ∼25 to 16 Ma (Davis et al., 1980). cataclastic and ultracataclastic rocks (including pseudo- Whipple Mountains metamorphic core complex (Figure 1 tachylyte), and (4) chlorite-epidote alteration of the mylo- and Table S1 of the auxiliary material), with most attention nites.

They are younger than or coeval with chloride brecciation, and those that record shear typically are either moderately northeast-dipping normal structures or steep, northwest-striking, southwest-down structures … Fabric and microstructural analyses of the thick (>3.5 km) mylonitic sequence indicate that it represents an intracrustal zone of non-coaxial laminar flow with a predominant sense of northeastward shear. Within the Whipple Mountains, the detachment fault often crops out as a ledge of impermeable micro breccia.
