Terra Nova, Volume 37, Issue 5, Page 316-323, October 2025.ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The relevance of work. In recent years much attention is paid to the problem of age identification of intrusive formations of the Eastern slope of the Middle, Northern and Prepolar Urals due to the absence of inclosing stratigraphic formations with ...

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract Formation of marginal sea basins is generally considered to be closely linked to mantle flow, but it is still ambiguous due to limited evidence from seismic anisotropy. Here, we investigate three‐dimensional shear‐wave azimuthal anisotropy in the lithosphere beneath the Philippine Sea Plate (PSP) and its surrounding regions.

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract The subduction of the Chile Ridge beneath South America beginning 12–16 Myr ago opened a gap in the subducting slab beneath southern Patagonia, which migrated northward and is located today at 46°S. Geodynamic processes associated with the slab window are poorly understood.

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract The uplift history of the Gangdese arc in Southern Tibet is fundamental to understanding when and how the plateau attained its current elevation and topographic relief. Detrital multi‐mineral provenance analysis of the Oligocene–Miocene strata in the intermontane Wuyu Basin provides new key information on the paleodrainage evolution in ...

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract Boundaries in the Phanerozoic chronostratigraphic scale are mainly precisely defined and dated, and many correspond to environmental catastrophes induced by the emplacement of LIPs. The pre‐Ediacaran geological timescale is currently subdivided by approximate absolute ages.
