Active Triclinic Transtension in a Volcanic Arc: A Case of the El Salvador Fault Zone in Central America

Geosciences, 2022
The El Salvador Fault Zone (ESFZ) is part of the Central American Volcanic Arc and accommodates the oblique separation movement between the forearc sliver and the Chortis block (Caribbean Plate).

The Santorini-Amorgos Shear Zone: Evidence for Dextral Transtension in the South Aegean Back-Arc Region, Greece

Geosciences, 2021
Bathymetric and seismic data provide insights into the geomorphological configuration, seismic stratigraphy, structure, and evolution of the area between Santorini, Amorgos, Astypalea, and Anafi islands.

Transtension at the Northern Termination of the Alfeo-Etna Fault System (Western Ionian Sea, Italy): Seismotectonic Implications and Relation with Mt. Etna Volcanism

Geosciences, 2022
Offshore data in the western Ionian Sea indicate that the NW–SE-trending dextral shear zone of the Alfeo-Etna Fault System turns to the N–S direction near the Ionian coastline, where the extensional Timpe Fault System is located.

Along-Strike Rapid Structural and Geomorphic Transition From Transpression to Strike-Slip to Transtension Related to Active Microplate Rotation, Papua New Guinea

Frontiers in Earth Science, 2021
The area of southeastern Papua New Guinea includes three active microplates – the Trobriand, Woodlark, and Solomon Sea plates – that are being deformed by regional convergence between the much larger Pacific and Australian Plates.

Orogenic Gold in Transpression and Transtension Zones: Field and Remote Sensing Studies of the Barramiya–Mueilha Sector, Egypt

Remote Sensing, 2019
Multi-sensor satellite imagery data promote fast, cost-efficient regional geological mapping that constantly forms a criterion for successful gold exploration programs in harsh and inaccessible regions.

SOURCES OF QUATERNARY POTASSIC VOLCANIC ROCKS FROM WUDALIANCHI, CHINA: CONTROL BY TRANSTENSION AT THE LITHOSPHERE–ASTHENOSPHERE BOUNDARY LAYER

Геодинамика и тектонофизика, 2016
Introduction. Transtension is a system of stresses that tends to cause oblique extension, i.e. combined extension and strike slip. Syn-volcanic transtensional deformations of the lithosphere may provide two possible scenarios for control of magmatic ...

The role of transtension and transpression in incipient collision: insights from offshore SE Taiwan

Geoscience Letters
Offshore SE Taiwan is regarded as the northern extension of the North Luzon Trough and reflects the early stages of arc–continent collision resulting from the oblique convergence between the Eurasian continental margin and the Luzon Arc.

Transtension driving volcano-edifice anatomy: Insights from Andean transverse-to-the-orogen tectonic domains

Quaternary International, 2017
Abstract Dykes and minor eruptive vents are not randomly distributed within tectonically controlled volcanic arcs, which is reflected in the resulting morphology of stratovolcanoes. As a first-order approach, regional stress field controls the spatial distribution and geometry of dykes and minor eruptive vents.
