Field observations from Gonto La (southern Tibet), a pass through the high Himalaya, reveal a continuous, planar, ~l&N-dipping detachment horizon (the Gonto La detachment). The detachment juxtaposes Tethyan dark slates over a footwall of extensive leucogranite of the Khula Kangri pluton, intruded into an injection complex layer regarded as an early Southern Tibet Detachment System (STDS) horizo...

Neogene extension in the Death Valley region, SE California, has produced a variety of sedimentary basins. Diachronous movements on an array of strike-slip and normal fault systems have resulted in the uplift and preservation of older basins in modern ranges. One of the best exposed of these is the Nova basin on the western flank of the Panamint Mountains. The Nova basin includes over 2000 m of...

As a product of hydrothermal mineralization at spreading centers, seafloor massive sulfides (SMS) have become research hotspot in the field prospecting and exploring deep-sea mineral resources owing to their enrichment various strategic metals. Since circulation changes magnetic properties host rocks can generate anomalies, near-bottom surveying is an effective method determine anomaly features...

We perform real-time measurements of the net contact area between two blocks of like material at the onset of frictional slip. We show that the process of interface detachment, which immediately precedes the inception of frictional sliding, is governed by three different types of detachment fronts. These cracklike detachment fronts differ by both their propagation velocities and by the amount o...

The Longmen Shan is the steepest topographic front at the India-Asia collision zone and the site of the Mw 7.9 Wenchuan earthquake. Here to explain the interseismic GPS velocities across the greater Longmen Shan region, we develop a boundary element model including earthquake cycle effects, topography, the westward dipping Beichuan Fault and a ∼20 km deep, shallowly dipping, detachment, inferre...

The relationships between brittle detachment faulting and ductile shear zones in metamorphic core complexes are often ambiguous. Although it is commonly assumed that these two structures kinematically linked genetically related, direct observations of this coupling rare. Here, we conducted a detailed field investigation to probe the connection fault mylonitic zone Ruby Mountain–East Humboldt Ra...

Balanced regional cross sections based on surface, seismic, and subsurface data show that the thin-skinned fold-and-thrust belt in Rocky Mountain Foothills of Kakwa area central Canadian Rockies consists a lower buried thrust developed Paleozoic Triassic strata an upper exposed faulted fold Jurassic to Cretaceous strata. Changes wavelength, amplitude, geometry with stratigraphic level indicate ...
