Shoshonites in Southern Tibet Record Late Jurassic Rifting of a Tethyan Intraoceanic Island Arc [PDF]

The Journal of Geology, 2007
Detailed field mapping combined with a petrologic and geochemical investigation of the Zedong terrane within the Yarlung Tsangpo suture zone provides insights to the evolution of now mostly subducted portions of Tethys during the Late Jurassic. The terrane is dominated by volcanic rocks of shoshonitic affinity, which were erupted in a submarine oceanic

LATE DEVONIAN VERKHNEURALSK VOLCANIC-PLUTONIC ASSOCIATION (EAST MAGNITOGORSK PALEOISLAND ARC, SOUTH URALS): AGE, PETROLOGY, GEOCHEMISTRY, ORE POTENTIAL AND GEODYNAMIC SETTING [PDF]

Минералогия
The geology and petrogeochemical features of the Verkhneuralsk volcanic-plutonic association in the South Urals are characterized. The relevance of the work is determined by necessary analysis of magmatic evolution of the region to clarify ideas on ...

Tertiary magmatism within the Republic of Macedonia: a review [PDF]

, 2001
Widespread Tertiary magmatism of both orogenic and within-plate signatures developed within the Macedonian part of the Dinarides. Orogenic magmatites (predominantly volcanic rocks) are present in 5 areas (from east to west): Osogovo-Besna Kobila ...

Subalkalic and calc-alcalic Early-Eifelian volcanicity and related pyrite-pollymetallic mineralization in the Magnitogorsk Megazone, the Southern Urals

Литосфера, 2017
Until now, there is a problem of the stratigraphic position and the serial petrogenetic affiliation of the Dzhusinsky volcanic complex and the correlation of the section of the Dzhusa-Dombarovka pyrite-palevolcanic belt of the East Magnitogorsk zone (EMZ)

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Magmatic History of Somma^Vesuvius on the Basis of New Geochemical and Isotopic Data from a Deep Borehole (Camaldoli dellaTorre)

, 2007
A continuous-coring borehole recently drilled at Camaldoli dellaTorre on the southern slopes of Somma^Vesuvius provides constraints on the volcanic and magmatic history of the Vesuvian volcanic area since c. 126 ka BP.

Chemical‐Thermomechanical Modeling of Open‐System Mass Transfer: Application to the Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract One of the main limitations in simulating subsolidus metasomatism is the decoupling between thermomechanical models and chemical/thermodynamic modeling. This decoupling amplifies the uncertainty associated with mass transport. Here, we introduce a fluid‐rock chemical‐thermomechanical interaction scheme, which integrates thermodynamic modeling (

Acid volcanism of various geotectonic situations (on the example of orogenic volcanic belts in Asia)

Литосфера, 2018
Acid volcanism (rocks with silica more than 64 wt%) is the most widely represented in the orogenic volcanic belts (continental margin and kollisional) and ensialic island arcs on the continental stage in their development.

Unveiling Cenozoic Volcanism in the Takab‐Shahindezh Area Induced by Slab‐Mantle Interaction in the Zagros Orogen, NW Iran

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Zagros orogen records the closure of the Neotethys Ocean by northward subduction of the oceanic slab beneath the Iranian plate. Northwestern Iran has undergone episodic volcanism since the Eocene, due to a shift of tectonic regimes from subduction to collision and post‐collisional extension, although the dynamics responsible for such ...

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, Volume 11, Issue 4, Page 1029-1062, September 2025.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...
