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 ...

Subduction Initiation and Mafic Intrusions: Rethinking the South China Sea-Luzon Connection

CT Lilun yu yingyong yanjiu
The conventional view suggests that the subduction of the South China Sea plate beneath Luzon occurred due to the oceanic lithosphere’s high density, facilitating subduction initiation.

Subduction Initiation Simulation Results

, 2017
How subduction initiates with mechanically unfavorable lithospheric heterogeneities is important and rarely studied. We investigate this with a geodynamic model for the Puysegur Incipient Subduction Zone (PISZ) south of New Zealand.

Earth's oldest mantle fabrics indicate Eoarchaean subduction

Nature Communications, 2016
Subduction is a main component of Phanerozoic plate tectonics, although the timing of initiation is controversial. Here, the authors present microstructural data from two 3.72 billion year old dunite lenses of Isua in Greenland, which suggest that ...

Post-ridge-subduction acceleration of the Indian plate induced by slab rollback

Solid Earth Sciences, 2018
The driving forces of plate motion, especially that of its sudden change over time, has long been debated. During the closure of an old ocean, the subduction process of the mid-ocean ridge provides valuable clues to quantitative evaluation of the driving

Initiation of Subduction Along Oceanic Transform Faults: Insights From Three-Dimensional Analog Modeling Experiments

Frontiers in Earth Science, 2018
Three-dimensional analog experiments are employed to explore how self-sustaining subduction may initiate along an oceanic transform fault. The models include a realistic spatial distribution of plate thickness, strength, and buoyancy of the lithosphere ...

Subduction zone initiation (SZI) Database

, 2020
The Subduction zone initiation (SZI) Database is a cross-disciplinary and community-driven approach to gain an improved understanding of subduction zone initiation (SZI) and overcome the key long-standing questions of the Earth Sciences of how, when and ...

Forearc Variability and the Geochemical Diversity of Suprasubduction Zone Ophiolites: Insights From the Leka Ophiolite Complex, Norway

Geochemistry, Geophysics, Geosystems
New whole‐rock major and trace element geochemistry from the Leka Ophiolite Complex in Norway is presented and compared to the geochemical evolution and proposed tectonomagmatic processes recorded in the Izu‐Bonin‐Mariana system.

Initiation of subduction by small‐scale convection [PDF]

Journal of Geophysical Research: Solid Earth, 2004
The possibility of initiation of subduction by sublithospheric small‐scale convection is investigated with the help of Fowler's theory, numerical constraints on the lithospheric stresses generated by convection, and direct numerical simulations of subduction.
