Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra-subduction zone ophiolites [PDF]

, 2015
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Horizontally forced initiation of the Izu-Bonin-Mariana subduction zone

Communications Earth & Environment
The sparsity of a direct record for the moment of subduction zone initiation has led to various models describing the infancy and evolution of modern oceanic subduction systems.

Do microcontinents nucleate subduction initiation?

, 2022
Subduction initiation is a pivotal process in plate tectonics. Models of subduction initiation include the collapse of passive margins, oceanic transform faults, inversion of oceanic core complexes, and ridge failure, but have ignored the potential effects of continental crust relics within the oceanic crust.

Inevitability of Plate Tectonics on Super-Earths [PDF]

, 2007
The recent discovery of super-Earths (masses less or equal to 10 earth-masses) has initiated a discussion about conditions for habitable worlds. Among these is the mode of convection, which influences a planet's thermal evolution and surface conditions ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Magmatic fingerprints of subduction initiation and mature subduction: numerical modelling and observations from the Izu-Bonin-Mariana system

Frontiers in Earth Science
Understanding the formation of new subduction zones is important because they have been proposed as the main driving mechanism for plate tectonics and they are crucial for geochemical cycles on Earth.

Reviewing subduction initiation and the origin of plate tectonics: What do we learn from present-day Earth?

Earth and Planetary Physics, 2021
The theory of plate tectonics came together in the 1960s, achieving wide acceptance after 1968. Since then it has been the most successful framework for investigations of Earth’s evolution. Subduction of the oceanic lithosphere, as the engine that drives
