Reappraisal of the Continental Rifting and Seafloor Spreading That Formed the South China Sea

open access: yesGeosciences
Recently published marine geophysical and seafloor drilling data permit a substantive reappraisal of the rifting and spreading that formed the South China Sea (SCS).

Riphean magmatism and ore formation, preceding the disclosure of the Uralian Paleoocean (western slope of the Southern Urals)

open access: yesЛитосфера, 2017
The analysis of the evolution of composition and mineral occurences of the Low and Middle Riphean magma-tic rocks from the riftogenic structures of the Bashkirian anticlinorium involving of some neighboring structures from the western slope of the ...

Flux Modulated Magmatic Architecture in Continental Magmatic Arcs

open access: yes
Petrochronology of the magmatic reservoir that underpinned the Chaxas Volcanic Complex for the duration of its 8.59 – 1.24 Ma lifecycle reveals that magmatic architecture can be regulated by magmatic flux. Modulation of the magmatic reservoir was controlled via two distinct flux regimes during the Pre-Chaxas and Chaxas Complex stages of the Chaxas ...

Neogene-Quaternary magmatic activity and its geodynamic implications in the Central Mediterranean region

open access: yesAnnals of Geophysics, 1997
The petrogenesis and time/space distribution of the magmatism associated with the formation of the Northern and Southern Tyrrhenian basins, together with the directions and ages of lithospheric extension and/or spreading north and south of the 410N ...

Upper cretaceous magmatic suites of the Timok magmatic complex

open access: yesGeoloski anali Balkanskoga poluostrva, 2010
The Upper Cretaceous Timok Magmatic Complex (TMC) developed on a continental crust composed of different types of Proterozoic to Lower Cretaceous rocks. The TMC consists of the magmatic suites: Timok andesite (AT) - Turonian-Santonian, Metovnica epiclastite (EM) - Coniacian-Campanian, Osnic basaltic andesite (AO) and Jezevica andesite (AJ) -

Evolution of melts and fluids during the crust and mantle formation in Neo-Archean—Paleo-Proterozoic. Stratigraphic effects

open access: yesГеофизический журнал, 2016
Evolution of composition of Precambrian magmatic and metamorphic rocks is related to directional change of deep fluids. It makes possible to use material composition of rocks as a sign for correlation.

Water budget in flat vs. steep subduction: implication for volcanism and potential for H2 production

open access: yesBSGF - Earth Sciences Bulletin
In this study, we model the processes of (de)hydration and melting within subduction zones using a thermo-mechanical modeling approach. Multiple 2D simulations are conducted to investigate how the subduction angle influences the water budget in oceanic ...

New insights into the evolution of hybrid rifted margins: from crustal hyperextension to mantle exhumation at the Santos Basin (Brazil)

open access: yesFrontiers in Earth Science
This study investigates the tectonic, magmatic and sedimentary architecture of the outer Santos Basin, using new ultra-deep high-resolution 3D seismic, gravimetric and magnetic data.
