Subduction initiation and the rise of the Shillong Plateau

Earth and Planetary Science Letters, 2020
Abstract Discrepancies between geodetically and geologically estimated thrust fault slip rates are generally viewed as a methodological problem. Even when slip rate is steady over geological time, a discrepancy may exist because each method is sensitive to different deformation processes.

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

Geological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Numerical modeling of subduction and evaluation of Philippine Sea Plate tectonic history along the Nankai Trough

Scientific Reports, 2023
The subduction of the Philippine Sea (PHS) plate along the Nankai Trough in in southwest Japan is a relatively recent process compared with subduction along the Japan Trench in northeast Japan.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

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.

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

Acta Geologica Sinica - English Edition, EarlyView.
High‐grade orebodies are controlled by stress field with σ1 oriented NE‐SW during the main mineralization stage.Inferred NEE‐trending strike‐slip fault control another orebody distribution. ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt.

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

Acta Geologica Sinica - English Edition, EarlyView.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo

Recognizing detachment-mode seafloor spreading in the deep geological past

, 2013
Large-offset oceanic detachment faults are a characteristic of slow- and ultraslow-spreading ridges, leading to the formation of oceanic core complexes (OCCs) that expose upper mantle and lower crustal rocks on the seafloor.

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.

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.
