Complementary geophysical, geomorphometric and pedological approaches for characterizing shallow and deep subsurface materials in a colluvial‐alluvial plain in Atlantic rainforest

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
This study combines GPR, 2D ERT and UAV‐derived terrain models to characterize sediment variability in a colluvial‐alluvial plain. GPR identified sandy lenses and clay‐rich layers, while ERT revealed deeper conductive and resistive zones, including a gneissic basement.

Stepwise magma migration and accumulation processes and their effect on extracted melt chemistry [PDF]

Estonian Journal of Earth Sciences, 2009
Numerical and analogue models suggest that melt production, its segregation from the solid matrix and subsequent transport and accumulation are highly dynamic and stepwise processes exhibiting scale invariant patterns in both time and length scales ...

Two Cycles of Devonian–Triassic Extension and Compression in the Altai Accretionary Wedge: Insights From Tsogt Core Complex

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

A Dual‐Geochronologic and Thermochronologic Detrital Approach to Identify the Focus of Erosion in the Kosi Basin, Nepal

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Kosi River watershed captures the major lithotectonic units, structures, and characteristic climatic conditions found along the Himalaya. Therefore, this setting provides a useful location to investigate the respective influences of tectonics and climate in eroding bedrock and driving landscape evolution.

Tectonometamorphic history of the Gruf complex (Central Alps): exhumation of a granulite-migmatite complex with the Bergell pluton [PDF]

, 2018
We describe field occurrences of sapphirine-bearing granulites, charnockites and migmatites in the Gruf complex, Central Alps and present a new geological map and a structural analysis of the entire Gruf complex for the first time. We have carried out an

The kinematic history of the Khlong Marui and Ranong Faults, southern Thailand [PDF]

, 2008
The Khlong Marui Fault (KMF) and Ranong Fault (RF) are major NNE-trending strike-slip faults which dissect peninsular Thailand. They have been assumed to be conjugate to the NW-trending Three Pagodas Fault (TPF) and Mae Ping Fault (MPF) in Northern ...

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Insights on high-grade deformation in quartzo-feldspathic gneisses during the early Variscan exhumation of the Cabo Ortegal nappe, NW Iberia [PDF]

Solid Earth, 2016
High-grade, highly deformed gneisses crop out continuously along the Masanteo peninsula and constitute the upper part of the lower crustal section in the Cabo Ortegal nappe (NW Spain).

Fast and Spatially Heterogeneous Cooling Rates at Amphibolite‐Facies Conditions in the Lepontine Alps (Switzerland)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The Lepontine dome (European Central Alps) is constituted by basement nappes under Alpine regional Barrovian metamorphism, yet the duration and pattern of its post‐peak amphibolite‐facies cooling remain uncertain. We examine garnet‐rim compositional re‐adjustment and employ inverse multicomponent diffusion modeling to estimate apparent cooling
