Magmatic and hydrothermal behavior of uranium in syntectonic leucogranites: The uranium mineralization associated with the Hercynian Guérande granite (Armorican Massif, France) [PDF]

, 2017
Most of the hydrothermal uranium (U) deposits from the European Hercynian belt (EHB) are spatially associated with Carboniferous peraluminous leucogranites.

The Impact of Orogenic Inheritance on Rifted Margin Formation

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Many rifted margins form within pre‐existing orogenic belts, emphasizing the significance of structural, thermal, and compositional inheritance in shaping rift dynamics. However, a key unresolved question is how these different types of orogenic inheritance individually influence rift evolution.

New magnetotelluric data through the boundary between the Ossa Morena and Centroiberian Zones [PDF]

, 2005
The south-western part of the Iberian Peninsula, including the southern branch of the Iberian Massif, has recently been the subject of several magnetotelluric (MT) studies.

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, Volume 61, Issue 1, Page 127-145, January 2026.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

A multidisciplinary study of a syntectonic pluton close to a major lithospheric-scale fault: relationships between the Montmarault granitic massif and the Sillon Houiller Fault in the Variscan French Massif Central. Part II: Gravity, aeromagnetic investigations and 3D geologic modeling. [PDF]

, 2008
International audienceNew gravity and aeromagnetic investigations have been carried out to understand the emplacement mechanisms of a granitic pluton and the relationships with a nearby lithospheric-scale fault.

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Isotopic Disequilibrium Between Migmatites and Protolith: Insights from a Variscan Anatectic Complex (NW of Iberian Variscan Belt, Portugal)

Geosciences
Isotopic disequilibrium during the formation of high-temperature (HT) metamorphic complexes by anatexis during continental collision is a process that deserves intense discussion since it is fundamental to understand the evolution of continental crust ...

Evidence of a Paleoproterozoic basement in the Moroccan Variscan [PDF]

, 2015
For the first time, an Eburnian magmatic event has been identified in the Rehamna Massif (Moroccan Variscan Belt, Western Meseta) located north of the South Meseta fault.

Syntectonic crustal melting and high-grade metamorphism in a transpressional regime, Variscan Massif Central, France [PDF]

, 2009
Hot collisional orogens are characterized by abundant syn-kinematic granitic magmatism that profoundly affects their tectono-thermal evolutions. Voluminous granitic magmas, emplaced between 360 and 270 Ma, played a visibly important role in the evolution

From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

Tectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...
