Linking deep and shallow crustal processes during regional transtension in an exhumed continental arc, North Cascades, northwestern Cordillera (USA)

open access: yes, 2016
The North Cascades orogen (northwestern USA) provides an exceptional natural laboratory with which to evaluate potential temporal and kinematic links between processes operating at a wide range of crustal levels during collapse of a continental arc, and ...

Pliocene Sinistral Slip across the Adobe Hills, Eastern California-Western Nevada: Kinematics of Fault Slip Transfer across the Mina Deflection [PDF]

open access: yes, 2013
The Adobe Hills region (California and Nevada, USA) is a faulted volcanic field located within the western Mina deflection, a right-stepping zone of faults that connects the northern Eastern California shear zone (ECSZ) to the south with the Walker Lane ...

Strain Localization Along Aphrodite Terra's Chasmata System, Venus: The Role of Frictional Melting and Fault‐Melt Interaction

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We analyze large‐scale shear zones that are exposed along the equatorial chasmata of Eastern Aphrodite Terra to understand the role of strain localization in the deformation of the Venusian crust. These shear zones dip at low angles opposite to the slopes, forming terraces that expose portions of the shear planes.

Interaction Between Transverse and Rift Faults During the Initiation of Orogenic Extension: The Case of Sant'Anna Pelago (Northern Apennines, Italy)

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract Sant'Anna Pelago is located near the extensional front of the Northern Apennines (Italy) between Modena and Lucca, an area characterized by multiple lateral steps of the NW‐SE striking tectonic system and orographic divide. The region is affected by significant instrumental seismicity with over a thousand recorded events (0.5 < M < 4.8) from ...

Guadalupe pluton–Mariposa Formation age relationships in the southern Sierran Foothills: Onset of Mesozoic subduction in northern California? [PDF]

open access: yes, 2009
We report a new 153 ± 2 Ma SIMS U-Pb date for zircons from the hypabyssal Guadalupe pluton which crosscuts and contact metamorphoses upper crustal Mariposa slates in the southern Sierra.

New active faults on Eurasian-Arabian collision zone : Tectonic activity of Özyurt and Gülsünler faults (eastern Anatolian Plateau, Van-Turkey) [PDF]

open access: yes, 2017
The Eastern Anatolian Plateau emerges from the continental collision between Arabian and Eurasian plates where intense seismicity related to the ongoing convergence characterizes the southern part of the plateau. Active deformation in this zone is shared

Transcurrent continental tectonics model [PDF]

open access: yes, 2004
The Ossa-Morena Zone (SW Iberian Massif) was affected by continuous orogen-parallel transcurrent continental tectonics from the Neoproterozoic to the Carboniferous times, involving transtension (TT) and transpression (TP) processes that co-existed ...
