Tectonics, Volume 45, Issue 2, February 2026.Abstract In the Central Alps, the Adula unit exposes high‐ and ultra‐high‐pressure (HP‐UHP) metamorphic rocks, providing key insights into the subduction and exhumation dynamics of the former distal European margin. We investigate the San Bernardino Shear Zone (SBSZ), a top‐to‐the‐east extensional shear zone developed within orthogneiss and paragneiss ...

Multianalytical provenance analysis of Eastern Ross Sea LGM till sediments (Antarctica): Petrography, geochronology, and thermochronology detrital data [PDF]
, 2017 In order to reveal provenance of detrital sediments supplied by West Antarctic Ice Sheet (WAIS), 19 glaciomarine cores of Last Glacial Maximum age were analyzed from Eastern Ross Sea and Sulzberger Bay.

Tectonics, Volume 45, Issue 2, February 2026.Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.

Tectonics, Volume 45, Issue 1, January 2026.Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...

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
