Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

Geochemistry, Geophysics, Geosystems
Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction ...

Factors on the Mesozoic Transition From Flat to Steep Subduction of the Paleo‐Pacific Plate Beneath South China: Thickened Oceanic Crust and Subduction Rate

Geochemistry, Geophysics, Geosystems, 2022
In the Mesozoic, the age of Paleo‐Pacific plate that flatly subducted beneath the South China was ∼80 Ma, resulting in a cold and dense oceanic slab. The transition process from flat to steep subduction of this old slab and factors that affect it are ...

Subduction-induced break-up and drifting of continental plates [PDF]

, 2022
Since the early theory of Wegener, the break-up and drift of continents have been controversial and hotly debated topics. To assist the interpretation of the break-up and drift mechanisms and its relation with mantle circulation patterns, we carried ...

Continental subductions and Tibetan plateau growth

Journal of Nepal Geological Society, 2013
How and when the Tibetan plateau developed has long been a puzzling question with implications for the current understanding of the behaviour of the continental lithosphere in convergent zones. We present and discuss recent data acquired in geology and geophysics and through igneous and metamorphic petrology and palaeo-altitude estimates. This research

Petrogenesis and Tectonic Setting of Late Mesozoic Felsic Magmatic Rocks in the Wangmushan Mining District, Northern Fujian, South China

Geological Journal, EarlyView.
The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

The Deep Structure of the Alps Based on the CIFALPS Seismic Experiment: A Synthesis

Geochemistry, Geophysics, Geosystems, 2021
The European Alps are the site where classic geologic concepts such as nappe theory, continental subduction and slab breakoff have been first proposed.

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence

International Journal of Climatology, EarlyView.
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

Compression-extension transition of continental crust in a subduction zone: A parametric numerical modeling study with implications on Mesozoic-Cenozoic tectonic evolution of the Cathaysia Block. [PDF]

PLoS ONE, 2017
The Cathaysia Block is located in southeastern part of South China, which situates in the west Pacific subduction zone. It is thought to have undergone a compression-extension transition of the continental crust during Mesozoic-Cenozoic during the ...

Uncoupled Histories in the Largest Continental Arc of North America: Goodeid Fishes and Their Gyrodactylid Parasites Influenced Differently by the Trans‐Mexican Volcanic Belt

Integrative Zoology, EarlyView.
• The Trans‐Mexican Volcanic Belt (TMVB) separates the Nearctic from the Neotropics. • TMVB's geology influenced diversification and distribution of endemic goodeid fishes. • Six neartic Gyrodactylus species infect goodeids within and north of the TMVB.

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems
Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt.
