Evidence for Miocene subduction beneath the Alboran Sea (Western Mediterranean) from 40Ar/39Ar age dating and the geochemistry of volcanic rocks from holes 977A and 978A [PDF]

, 1999
Volcanic pebbles in gravels from Sites 977 and 978 in the Alboran Sea (western Mediterranean) were dated (using the 40Ar/ 39Ar single-crystal laser technique) and analyzed for their major- and trace-element compositions (determined by X-ray ...

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Arc-parallel vs back-arc extension in the Western Gibraltar arc : is the Gibraltar forearc still active? [PDF]

, 2012
Extremely tight arcs, framed within the Eurasia-Africa convergence region, developed during the Neogene on both sides of the western Mediterranean. A complex interplate deformation zone has been invoked to explain their structural trend-line patterns ...

Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined. We present new geochemical data from the middle crust of the Kohistan Arc and use existing geochemical and geochronological literature data from this arc to ...

Multiple subduction imprints in the mantle below Italy detected in a single lava flow [PDF]

, 2016
Post-collisional magmatism reflects the regional subduction history prior to collision but the link between the two is complex and often poorly understood.

Contribution of the Rheologically Weak Lower Crust to Contemporary Crustal Motions in the Southeastern Tibetan Plateau, China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern Tibetan Plateau (SETP) plays a pivotal role in accommodating intra‐continental deformation driven by the ongoing India‐Eurasia convergence. However, its contemporary surface vertical motions and the underlying geodynamic processes remain highly debated.

Sedimentation record in the Konkan-Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin [PDF]

, 2007
The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin.

Periodic void formation in chevron folds

, 2014
An energy-based model is developed to describe the periodic formation of voids/saddle reefs in hinge zones of chevron folds. Such patterns have been observed in a series of experiments on layers of paper, as well as in the field.
