Reappraisal of the Continental Rifting and Seafloor Spreading That Formed the South China Sea

open access: yesGeosciences
Recently published marine geophysical and seafloor drilling data permit a substantive reappraisal of the rifting and spreading that formed the South China Sea (SCS).

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, Volume 67, Issue 5, Page 1195-1211, October 2025.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Fluid or Melt? Distinguishing Syn‐Deformational Interaction Pathways

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 8, Page 810-838, October 2025.
ABSTRACT Understanding whether deformation occurred in the presence of aqueous fluid or silicate melt is crucial for interpreting ductile shear zones, impacting their thermal and geochemical evolution, and having rheological consequences. To identify the syn‐deformational fluid type, we investigate contrasting shear zones active during the Alice ...

Riphean magmatism and ore formation, preceding the disclosure of the Uralian Paleoocean (western slope of the Southern Urals)

open access: yesЛитосфера, 2017
The analysis of the evolution of composition and mineral occurences of the Low and Middle Riphean magma-tic rocks from the riftogenic structures of the Bashkirian anticlinorium involving of some neighboring structures from the western slope of the ...

A Paleotectonic Atlas of the African Plate: Permian to Recent

open access: yesJournal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Intermittent Brittle and Ductile Deformation as Recorded by Dating of Ultramylonites and Pseudotachylytes in Extending Continental Crust (Ivrea‐Verbano Zone, Italy)

open access: yesTerra Nova, Volume 37, Issue 5, Page 277-286, October 2025.
ABSTRACT Mylonites and pseudotachylytes play a crucial role in defining the rheology of extending continental crust. In this context, determining the age of brittle‐ductile deformation is fundamental to understanding the rifting evolution stages. Here, we investigate the Premosello Shear Zone, an extensional structure of the Ivrea‐Verbano lower crust ...
