Fluid Dynamics in a Thrust Fault Inferred from Petrology and Geochemistry of Calcite Veins: An Example from the Southern Pyrenees

open access: yesGeofluids, 2020
Petrographic and geochemical analyses (δ18O, δ13C, 87Sr/86Sr, clumped isotopes, and elemental composition) coupled with field structural data of synkinematic calcite veins, fault rocks, and host rocks are used to reconstruct the episodic evolution of an ...

Width of surface rupture zone for thrust earthquakes: implications for earthquake fault zoning [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2018
The criteria for zoning the surface fault rupture hazard (SFRH) along thrust faults are defined by analysing the characteristics of the areas of coseismic surface faulting in thrust earthquakes.

Accelerating slip rates on the Puente Hills blind thrust fault system beneath metropolitan Los Angeles, California, USA [PDF]

open access: yes, 2017
Slip rates represent the average displacement across a fault over time and are essential to estimating earthquake recurrence for probabilistic seismic hazard assessments.

Southwest extension of dextral transpression along the Burnsville fault into the Clyde 7.5-minute quadrangle, western North Carolina, USA

open access: yesJournal of Maps, 2020
The Neoacadian Burnsville fault is a dextral transpressional structure exposed in western North Carolina. Bedrock geologic mapping in the Clyde 7.5-minute quadrangle documents the fault an additional ∼40 km southwest than previously mapped.

On the growth of normal faults and the existence of flats and ramps along the El Asnam active fold and thrust system [PDF]

open access: yes, 1992
The combination of detailed topographic leveling on the southwest segment of the El Asnam thrust fault with existing seismic and geologic data implies that the geometry of this fault involves shallow dipping flats and steep ramps. The fault appears to be

Active folding of fluvial terraces across the Siwaliks Hills, Himalayas of central Nepal [PDF]

open access: yes, 2000
We analyze geomorphic evidence of recent crustal deformation in the sub-Himalaya of central Nepal, south of the Kathmandu Basin. The Main Frontal Thrust fault (MFT), which marks the southern edge of the sub-Himalayan fold belt, is the only active ...

Study of overthrust nappe structure and its geodynamic mechanism along the southeastern margin of Nansha Trough

open access: yesChina Geology, 2018
: On the basis of interpretation of comprehensive geophysical data and foreign data analysis, there existed a lot of overburden detachment shear thrust faults along the southeastern margin of Nansha Trough, which composed imbricated overthrust nappe ...

Fault Slip and Exhumation History of the Willard Thrust Sheet, Sevier Fold‐Thrust Belt, Utah: Relations to Wedge Propagation, Hinterland Uplift, and Foreland Basin Sedimentation [PDF]

open access: yes, 2019
Zircon (U‐Th)/He (ZHe) and zircon fission track thermochronometric data for 47 samples spanning the areally extensive Willard thrust sheet within the western part of the Sevier fold‐thrust belt record enhanced cooling and exhumation during major thrust ...

Geological Structure of the Sylmar Basin: Implications for Slip Distribution Along the Santa Susana/Hospital and Mission Hills Fault System in the San Fernando Valley, CA, U.S.A.

open access: yesFrontiers in Earth Science, 2021
We developed a forward model using the Trishear module in MOVE to better understand the structure of the northwestern San Fernando Valley and the relationship among the Santa Susana, Hospital, Mission Hills and Northridge Hills faults.

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

open access: yes, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...
