It is commonly assumed a thrust has constant slip and uplifting rate along strike, however, this simplified model cannot always be consistent with field observations. The strike patterns variable offsets rates contain plenty of information about the characteristics faulting behavior its relationship adjacent faults. east Qilian Shan, located at northeastern margin Tibetan Plateau, provides us a...

The Semail Thrust in the Oman-UAE mountains is mapped along base of Ophiolite, a 10–15 km thick sequence Cenomanian oceanic crust and upper mantle emplaced from NE to SW onto previously passive, Mid-Permian continental margin Oman. juxtaposition ophiolite with range different rock types sourced depths suggest complex tectonic history for this major fault shear zone. Here we summarize previous w...

An integrated petrologic, thermochronologic, and numerical modeling study constrains the thermal evolution of the Lesser Himalayan Sequence in the Kumaun and Garwhal regions of India. South of the Tons thrust, peak metamorphic temperatures do not exceed 330 °C. On the northern side, a transition toward higher temperatures adjacent to the Main Central thrust hanging wall is documented. In the im...

The Rembrandt basin is crosscut by the largest fault scarp on Mercury, Enterprise Rupes, and a second scarp complex, Belgica Rupes, extends to the basin’s rim. Topographic data derived fromMESSENGER orbital stereo images show that these tectonic landforms bound a broad, relatively flat-floored valley with a mean width of ~400 km. Crosscutting relations suggest that the accumulation of structura...

Two large-scale north-dipping, low-angle normal faults cut the Everest massif at the top of the High Himalayan slab in Nepal. The upper fault the Qomolangma Detachment, follows the north slope of Everest from above the ‘Yellow Band’ at c. 8500 m on the Southwest Face down to the Rongbuk glacier. On the south side of Everest this fault places unmetamorphosed Ordovician mudstones and limestones a...

Teleseismic body waveform modeling of the far-field P-and SH-waveforms and spectral analysis of P-waves are used to determine the source parameters of the March 25, 2006 Fin earthquake (mb 5.7). Its epicenter is located at the South of Iran in Hormozgan Province. The waveform modeling results show the earthquake was caused by a thrust motion on a NW-SE striking fault with parameters: Fault plan...

The 17 December 2016 Solomon Islands earthquake (Mw 7.9) initiated ~103 km deep in the subducting Solomon Sea slab near the junction of the Solomon Islands and New Britain trenches. Most aftershocks are located near the Solomon Islands plate boundary megathrust west of Bougainville, where previous large interplate thrust faulting earthquakes occurred in 1995 (Mw 7.7) and 1971 (Mw 8.0). Teleseis...

Two faults define structural domains with varying geological and “reservoir” characteristics such as thickness and structural complexity; these are the Yamaska Normal Fault to the North and the Logan line, a thrust feature to the south is mapable at surface (Fig.1) . Talisman has a large acreage in the area and focus its attention on the Utica shale which is more laterally uniform, easier to un...

[1] We analyze the kinematics of fault tip folding at the front of a fold-and-thrust wedge using a sandbox experiment. The analog model consists of sand layers intercalated with low-friction glass bead layers, deposited in a glass-sided experimental device and with a total thickness h = 4.8 cm. A computerized mobile backstop induces progressive horizontal shortening of the sand layers and there...
