Strike-slip duplexes

open access: yesJournal of Structural Geology, 1986
Abstract Strike-slip fault systems often contain zones of steep imbricate faults geometrically similar to imbricate fans and duplexes in dip-slip, thrust and normal, fault systems. They are evident in map view rather than in vertical sections. Examples of duplexes are cited from both active and ancient systems and from theoretical and physical models.

Equal spacing of strike-slip faults [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976
Summary Strike-slip fault systems on continents frequently occur in groups of several roughly equally-spaced faults. In this article these systems are simulated by a model. A physical mechanism is then presented, which appears to explain the phenomena shown by the model both qualitatively and to a certain extent quantitatively.

The Advances and Challenges of the Ediacaran Fractured Reservoir Development in the Central Sichuan Basin, China

open access: yesEnergies, 2022
The largest Precambrian gasfield in China has been found in the central Sichuan Basin. It has been assumed as an Ediacaran (Sinian) mound–shoal, microfacies-controlled, dolomite reservoir.

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]

open access: yes, 2009
The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

Compression at Strike‐Slip Fault Is a Favorable Condition for Subduction Initiation

open access: yesGeophysical Research Letters, 2023
The recent statistics suggests that over 60% of active Cenozoic subduction initiation (SI) cases are related to the strike‐slip fault. A number of previous studies have shown that the lithospheric weak zone is a necessary condition for the SI.

Superficial simplicity of the 2010 El Mayor–Cucapah earthquake of Baja California in Mexico [PDF]

open access: yes, 2010
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures.

Using historical aerial images to accurately locate the urban "invisible" active faults: A case study of the Shuiyu fault of the Datong Basin in Shanxi province

open access: yesDizhi lixue xuebao, 2021
Active fault is a major risk source of urban earthquake disaster. Accurately identifying the spatial geometry distribution features of active fault is the basis for urban seismic risk migration.

Strike-slip relay ramps

open access: yesJournal of Structural Geology, 1995
Areas of reorientated bedding at contractional oversteps between strike-slip faults are here called strike-slip relay ramps. Metre-scale examples are described from the Jurassic sediments at East Quantoxhead, Somerset U.K. Larger strike-slip relay ramps occur in the Rio de Peixe Basin, NE Brazil, along the Newport-Inglewood Trend, California, and in ...

Strike-slip faults and their significance for hydrocarbon accumulation in Gaoshiti–Moxi area, Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2018
Based on the three dimensional seismic data and drilling data in Gaoshiti–Moxi area, the structural characteristics and evolution process of strike-slip faults in the study area and their significance for gas accumulation were examined using the method ...

Is the Jurassic (Yanshanian) intraplate tectonics of North China due to westward indentation of the North China block? [PDF]

open access: yes, 2012
International audienceThe northern mountains of Beijing are the type locality of the Mesozoic Yanshanian orogen. Our structural study emphasizes the importance of dextral strike-slip for the formation of this intracontinental belt.
