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 yanjiuThe 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.

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 ...

The subduction initiation stage of the Wilson cycle [PDF]
Geological Society, London, Special Publications, 2018 Abstract In the Wilson cycle, there is a change from an opening to a closing ocean when subduction begins. Subduction initiation is commonly identified as a major problem in plate tectonics and is said to be nowhere observable, yet there are many young subduction zones at the west Pacific margins and in eastern Indonesia.

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

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 ...

Temporal evolution of mantle wedge oxygen fugacity during subduction initiation [PDF]
, 2015 Arc basalts have a higher proportion of Fe in an oxidized state (Fe^(3+)) relative to Fe^(2+) compared to mid-oceanic ridge basalts (MORBs), likely because slab-derived fluids oxidize the mantle wedge where subduction zone magmas originate. Yet, the time

BONINITES THROUGH TIME AND SPACE: PETROGENESIS AND GEODYNAMIC SETTINGS
Геодинамика и тектонофизика, 2016 The article provides an overview of boninitic magmatism occurrences in space and time and shows that the boninite rock series were generated through the entire geological history of the Earth.
