Migrated Teleseismic P Wave Receiver Functions Reveal Intricate Post‐Subduction Crust and Upper Mantle Structure of Northern Borneo (Sabah), Malaysia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract Borneo is a key piece of the regional tectonic puzzle of southeast Asia and a unique location to study subduction termination, particularly in the north. The tectonic history of Sabah in northern Borneo includes elements of five different subduction events: (a) westward Triassic Palaeo‐Pacific (∼240–200 Ma); (b) southward Cretaceous proto ...

Domino structures as a local accommodation process in heterogeneous shear zones [PDF]

open access: yes, 2013
Usually, deformation in rocks is heterogeneously distributed, concentrating on planar zones located between rigid blocks, named shear zones. The geometry and kinematic criteria analysis becomes essential to understand the shear zones dynamics; the ...

The concealed Caledonide basement of eastern England and the southern North Sea : a review [PDF]

open access: yes, 1995
Field mapping, analysis of borehole core and studies of geophysical potential field and seismic data can be used to demonstrate the existence of a number of distinct crustal blocks within Eastern Avalonia beneath eastern England and the southern North ...

Characterization of Diffusion‐Creep Olivine Fabric and Its Identification in Natural Peridotite: Repeated Pure Shear and Equal‐Channeling Angular Pressing Tests

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract We performed repeated pure shear and equal‐channel angular pressing tests on Fe‐free olivine +10 or 20 vol% diopside aggregates to investigate the characteristics of crystallographic preferential orientation (CPO) development in olivine during diffusion creep.

SIR-A imagery in geologic studies of the Sierra Madre Oriental, northeastern Mexico. Part 1 (Regional stratigraphy): The use of morphostratigraphic units in remote sensing mapping [PDF]

open access: yes
SIR-A imaging was used in geological studies of sedimentary terrains in the Sierra Madre Oriental, northeastern Mexico. Geological features such as regional strike and dip, bedding, folding and faulting were readily detected on the image. The recognition

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

open access: yes, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Tectonique transpressive en terre Adélie au Paléoprotérozoı̈que (Est Antarctique)

open access: yesComptes Rendus. Géoscience, 2002
Le secteur paléoprotérozoı̈que de terre Adélie montre deux types de domaines structuraux synchrones de conditions métamorphiques HT–BP : des dômes et des zones de cisaillement verticales subméridiennes. Les zones de cisaillement résultent d'un régime transpressif dextre.

Contemporaneous Stress in Taiwan: Evidence for Orogen‐Parallel Extension and Lower Crustal Extrusion

open access: yesTectonics, Volume 44, Issue 11, November 2025.
Abstract Syn‐to late‐orogenic extension caused by gravitational collapse is a process that has been documented in most orogens. In this paper, we investigate the contemporaneous stress field in Taiwan to examine syn‐orogenic extensional faulting and the possible gravitational collapse modes by which it is taking place.

GEODYNAMIC ACTIVITY OF MODERN STRUCTURES AND TECTONIC STRESS FIELDS IN NORTHEAST ASIA

open access: yesГеодинамика и тектонофизика, 2017
Based on the analysis of changes in the stress-strain state of the crust at the boundary of the Eurasian and North American tectonic plates, we develop a dynamic model of the main seismogenerating structures inNortheast Asia.

Zircon geochronology of intrusive rocks from Cap de Creus, eastern Pyrenees [PDF]

open access: yes, 2014
New petrological and U–Pb zircon geochronological information has been obtained from intrusive plutonic rocks and migmatites from the Cap de Creus massif (Eastern Pyrenees) in order to constrain the timing of the thermal and tectonic evolution of this ...
