Restoring the Missing Late Cretaceous Arc of Iran

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract 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. During Neo‐Tethys subduction under Iran, there was pulsed arc magmatism with Middle Jurassic and Eocene magmatic flare‐ups ...

A review of the NE Atlantic conjugate margins based on seismic refraction data [PDF]

open access: yes, 2016
The NE Atlantic region evolved through several rift episodes, leading to break-up in the Eocene that was associated with voluminous magmatism along the conjugate margins of East Greenland and NW Europe.

Finite‐Frequency Tomography of the Upper Mantle Beneath the Proterozoic Capricorn Orogen in the Central West Australian Craton

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Capricorn Orogen, central to the West Australian Craton (WAC) and flanked by the Pilbara Craton to the north and the Yilgarn Craton to the south, records complex tectonic processes spanning from the Archean to the Neoproterozoic, including two major Paleoproterozoic collisions—the 2,215–2,145 Ma Ophthalmia Orogeny and the 2,005–1,950 Ma ...

3D Petro‐Structural Evolution of the High Pressure‐Low Temperature Phyllite‐Quartzite Nappe Pile in Southern Peloponnese, Greece

open access: yesTectonics, Volume 44, Issue 12, December 2025.
Abstract Tectonic underplating of high‐pressure/low‐temperature (HP‐LT) tectonic slices is a key mechanism in crustal growth at convergent margins. Yet, the processes controlling the geometry, depth and sequence of underplating events remain poorly constrained.

Coeval Early Ediacaran Breakup of Amazonia, Baltica, and Laurentia: Evidence From Micro‐Baddeleyite Dating of Dykes From the Novillo Canyon, Mexico

open access: yesGeophysical Research Letters, 2019
Final Rodinia supercontinent breakup during the early Ediacaran is recorded by mafic dyke swarms in Baltica and Laurentia, but corresponding dykes have been elusive for Amazonia, the third craton involved.

Tracing the Syn‐Convergence Extrusion Tectonics of the Sulu Orogenic Belt and Its Implication for North China–South China Collision

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Understanding the transition from oceanic to continental subduction is critical for reconstructing the geodynamic evolution of orogens and constraining ancient plate boundaries. The Sulu orogenic belt in eastern China was formed by Triassic deep subduction of the South China Block (SCB) beneath the North China Block (NCB). Its architecture was

Application Power Spectrum Analysis of Gravity Data to Investigate Subsurface Structures of the North Banggai-Sula Microcontinent in Maluku Sea Area

open access: yesIraqi Geological Journal
Different tectonic characteristics are exhibited among Maluku Sea and Banggai-Sula Microcontinent which are located side by side to each other. However, the northern part of the Banggai-Sula Microcontinent, positioned along the Maluku Sea margin,

Petrology of porphyritic quartz monzodiorite stock and Eocene dykes with adakitic nature from SW of Jandaq (NE of Isfahan province); Evidence of oceanic crust subduction around the Central-East Iranian Microcontinent

open access: yesJournal of Economic Geology, 2019
The “adakite” term was used for the first time by Defant and Drummond (1990) to display Cenozoic arcs igneous rocks with intermediate composition (SiO2> 56 wt.%), which were produced by partial melting of subducted oceanic crust.

Insights on the kinematics of the India-Eurasia collision from global geodynamic models [PDF]

open access: yes, 2012
The Eocene India-Eurasia collision is a first order tectonic event whose nature and chronology remains controversial. We test two end-member collision scenarios using coupled global plate motion-subduction models. The first, conventional model, invokes a
