Late Neoproterozoic adakitic magmatism of the eastern Arabian Nubian Shield
, 2018 Late Neoproterozoic adakitic magmatism within the Eastern Arabian Nubian Shield has been dated at 633.2 ± 9.0 Ma (2σ). These magmas intrude the forearc Ad Dawadimi Basin, which is composed of metapelitic schists and greywacke along with ophiolitic ...

Tertiary To Present Evolution Of Orogenic Magmatism In Italy
, 2010 : Tertiary to present magmatism in Italy is related to the convergence between the African and European plates. The Alpine orogeny and magmatism are the result of eastward and southward subduction of the Tethys ocean basin beneath the Adriatic ...

, 2015 Intraplate magmatism is pervasive within both oceanic and continental crust. Expansive spatially and across geologic time, it is complex because of both its causative magmatic processes as well as its interplay with Earth’s mantle geodynamics and plate

Sublithospheric small-scale convection: a mechanism for collision zone magmatism [PDF]
, 2014 We studied the effect of increased water content on the dynamics of the lithosphere-asthenosphere boundary in a postsubduction setting. Results from numerical mantle convection models show that the resultant decrease in mantle viscosity and the ...

Deccan-related magmatism west of India-Seychelles rift
, 1992 The rocks of the Seychelles can be divided into two age groups, namely Precambrian granites and younger (Cretaceous/Tertiary) intrusive rocks. The latter can be further subdivided into alkaline ring complexes (as found on the islands of Silhouette and ...

CO2 magmatism in Italy: from deep carbon to carbonatite volcanism
, 2007 The importance of CO2 in the Italian mantle and magmatism is supported by the presence of Middle-Upper Pleistocene carbonatites along the Italian Apennine graben-systems.

Magmatism and Geothermal Potential in Pandan Volcano East Java Indonesia
, 2019 Pandan volcano is a volcano formed on Tertiary sedimentary rocks from the Kendeng zone deposited in the basin of East Java. In addition to generating petroleum potentials, such as Cepu and Bojonegoro oil fields, this area also generates geothermal ...

Water budget in flat vs. steep subduction: implication for volcanism and potential for H2 production
BSGF - Earth Sciences BulletinIn 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 ...

Upper cretaceous magmatic suites of the Timok magmatic complex
Geoloski 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) -
