Geologic, geomorphic, and geophysical analyses of landforms, sediments, and structures in northern Cache Valley, USA, document a revised history of flooding and recession of Lake Bonneville, the world's premier pluvial lake. Crosscutting relationships suggest that the Riverdale fault produced a surface-rupturing earthquake ∼25 km southeast of Zenda shortly before, during, or after the Bonneville flood, as well as possible younger surface ruptures. Thus fluctuating stresses and pore pressure induced by changing lake levels may have triggered a large earthquake that, in turn, triggered the Bonneville flood. The flood scoured ∼25 km of Cache and Marsh Valleys and activated landslides during …

http://lithosphere.geoscienceworld.org/content/1/4/206 The San Andreas Fault Observatory at Depth (SAFOD) drill hole encountered indurated, high-seismic-velocity arkosic sedimentary rocks west of the active trace of the San Andreas fault in central California. The arkosic rocks are juxtaposed against granitic rocks of the Salinian block to the southwest and against fine-grained Great Valley Group and Jurassic Franciscan rocks to the northeast. We identify three distinct lithologic units using cuttings, core petrography, electrical resistivity image logs, zircon fission-track analyses, and borehole-based geophysical logs. The upper arkose occurs from 1920 to 2530 m measured depth (mmd) in the borehole and is composed of five structural …

Cenozoic Extensional Processes And Tectonics In The Northern Rocky Mountains, Susanne U. Janecke
Susanne U. Janecke
Extension has shaped the crust of the Northern Rocky Mountains for more than a billion years. Rifting produced the Belt basin shortly after 1.5 Ga and initiated the Paleozoic passive margin. Mesozoic to early Cenozoic convergence pro-duced the Cordilleran fold-and-thrust belt, the uplifts of the Rocky Mountain foreland (Laramide) and an unusually broad Challis arc in the northern Rocky Mountains. The struc-tural grain of the contractional belts, basement features, and the rheology of the Idaho batho-lith influenced the locus, kinematics and ge-ometry of the >55 m.y. of extension that fol-lowed. Sparse data suggest that extension may have begun in the …

Uplift and exposure of the Bannock detachment system and the synextensionalbasin fi ll deposits of the Salt Lake Formation provide a unique exposure of the threedimensionalgeometries of a low-angle normal fault system and the stratal architectureof the overlying supradetachment basin. Within this system, structural andstratigraphic analyses, outcrop patterns, tephra geochronology, and geological crosssections document several important relationships: (1) the Bannock detachment systemdeveloped above the Sevier-age Cache-Pocatello culmination and resembles theSevier Desert detachment in its geometry, structural setting, and kinematic evolution;(2) the Bannock detachment system initiated and slipped at low angles; (3) fl aton-fl at, ramp-fl at, and lateral ramp geometries, …
