The engineering geology of the Nottingham area, UK [PDF]

, 2009
Nottingham was built near a crossing point on the River Trent in the East Midlands of England. Initially, the City developed on a low sandstone hill close to the north bank of the river, which provided a secure, well-drained location above the marshes ...

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Shelf-Ocean material exchange influencing the Atlantic chemical composition off NW Iberian margin since the last glaciation [PDF]

, 2010
Rivers are the main conduit of sediment to the shelf. The basin geology, the drainage area and the discharge rate are the major factors that determine their sediment load (Milliman and Syvistski, 1992).

Seismicity and Seismotectonics in the Cantabrian‐Pyrenean Zone (N Spain) Using a Dense Temporary Network of Broadband Seismic Stations

Tectonics, Volume 45, Issue 3, March 2026.
Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

Late Ediacaran juvenile magmatism in the Variscan Monts-du-Lyonnais metamorphic complex (Massif Central, France)

BSGF - Earth Sciences Bulletin
The identification of oceanic sutures is key to understanding the evolution of the Paleozoic Variscan belt and the structure of the West European lithosphere.

Flow of partially molten crust controlling construction, growth and collapse of the Variscan orogenic belt: the geologic record of the French Massif Central

BSGF - Earth Sciences Bulletin, 2020
We present here a tectonic-geodynamic model for the generation and flow of partially molten rocks and for magmatism during the Variscan orogenic evolution from the Silurian to the late Carboniferous based on a synthesis of geological data from the French

Distribution of natural radionuclides in the soils and assessment of radiation hazards in the Khrami Late Variscan crystal massif (Georgia)

Heliyon, 2019
This study was performed to determine the distributions of radionuclides (238U, 232Th and 40K naturally occurring in Khrami Late Variscan crystal massif and soils overlapping its adjacent territory built by Neogene and Quaternary lava using a gamma-ray ...

New geochemical and isotopic constraints on the genesis of the Oliveira Azeméis granitoid melts (Porto-Tomar Shear Zone, Iberian Variscan Chain, Central-Western Portugal). [PDF]

, 2012
The Porto-Tomar Shear Zone (PTSZ) is a very important tectonic structure that separates, in central-western Portugal, two of the major tectonic units of the Iberian Variscan Chain: the Ossa-Morena Zone, to the west, and the Central Iberian Zone, to the ...

Analysis of the Importance of Extension in Accounting for the Post-Carboniferous Subsidence of the North Sea Basin [PDF]

, 1986
Post Carboniferous sedimentary deposition in the Central North Sea basins can be separated into three major periods: Permian, Triassic and mid-Jurassic through present.
