Geodynamic modelling of subduction zones : Subduction zone initiation by polarity reversal and main dynamic controls on the stability of single-sided subduction

, 2021
Subduction zones are one of the most widely studied geodynamic settings, representing the primary driver for mantle convection and plate tectonics.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

RRS "Charles Darwin" Cruise 178, 14 Mar - 11 Apr 2006. 3D seismic acquisition over mud volcanoes in the Gulf of Cadiz and submarine landslides in the Eivissa Channel, western Mediterranean Sea [PDF]

, 2006
The major aims of Charles Darwin Cruise 178 were to obtain (i) 3D seismic imagery, video transects and swath bathymetry maps of mud volcanoes in the southern Gulf of Cadiz, (ii) video transects across suspected cold water coral reefs in the Alboran Sea ...

Serpentinites and serpentinites within a fossil subduction channel: La Corea mélange, eastern Cuba

Geologica Acta, 2011
A variety of metaultramafic (serpentinite) rocks in La Corea mélange, Sierra de Cristal, eastern Cuba, show differences in chemical, textural and mineralogical characteristics demonstrating a variety of protoliths.

Inferring the Paleo‐Location of Proto‐Arc Magmas During Subduction Infancy in the Izu‐Bonin‐Mariana

Geochemistry, Geophysics, Geosystems
Subduction zones are one of the principal drivers of the modern‐day plate tectonics, but the processes that develop as incipient subduction zones mature are yet to be understood.

Exhumation of high‐pressure metamorphic rocks in a subduction channel: A numerical simulation [PDF]

Tectonics, 2002
High‐pressure metamorphic rocks provide evidence that in subduction zones material can return from depths of more than 100 km to the surface. The pressure‐temperature paths recorded by these rocks are variable, mostly revealing cooling during decompression, while the time constraints are generally narrow and indicate that the exhumation rates can be on

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]

, 2011
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

Evidence for Miocene subduction beneath the Alboran Sea (Western Mediterranean) from 40Ar/39Ar age dating and the geochemistry of volcanic rocks from holes 977A and 978A [PDF]

, 1999
Volcanic pebbles in gravels from Sites 977 and 978 in the Alboran Sea (western Mediterranean) were dated (using the 40Ar/ 39Ar single-crystal laser technique) and analyzed for their major- and trace-element compositions (determined by X-ray ...

Dynamics of intraoceanic subduction initiation: 2. Suprasubduction zone ophiolite formation and metamorphic sole exhumation in context of absolute plate motions [PDF]

, 2015
Analyzing subduction initiation is key for understanding the coupling between plate tectonics and the underlying mantle. Here we focus on suprasubduction zone (SSZ) ophiolites and how their formation links to intraoceanic subduction initiation in an ...
