Post‐Collisional Evolution in the Southern Variscan Belt: Insights From Numerical Modeling of the Valpelline Series (Western Alps)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The post‐collisional evolution of orogenic belts is commonly marked by high‐temperature metamorphism and widespread magmatism, yet the processes linking collision to post‐collisional dynamics remain difficult to reconstruct due to limited exposure of deep‐crustal levels and uncertainties in the determination of pressure‐temperature conditions ...

Chemical mineralogy and illite crystallinity in low grade metasediments, Zarouchla Group, northern Peloponnesus, Greece

open access: yes, 1991
Low grade metasediments from the Zarouchla Group of the Phyllite-Quartzite series in northern Peloponnesus have been investigated. Mineralogically, there is a clear distinction between the lowermost and the overlying formations.

Sub-Basaltic sediments and metasediments of Mersey- Forth Area

open access: yesPapers and proceedings of the Royal Society of Tasmania, 1967
Lacustrine sediments and silicified river gravels, slope deposits, in situ weathered material and joint fillings of Tertiary age in the Mersey-Forth area are described. An assessment is made of Tertiary drainage directions and the degree of post-basalt downcutting.

Comparison of metamorphic evolution and tectonic position of metasediments of the Austevoll islands with rocks from the Samnanger Complex (Major Bergen Arc, Norwegian Caledonides) [PDF]

open access: yes, 2015
Metasedimentary rocks represent a substantial component of the Bergen Arcs System and they are mostly confined to the Minor and Major Bergen Arcs. The arcs represents imbricate structures composed of island arc lithologies, prism sediments and gneissic ...

High-pressure metasediments in central Turkey: Constraints on the Neotethyan closure history

open access: yes, 2010
The distribution of oceanic domains and continental blocks in Central Anatolia remains a challenge in understanding the Alpine geodynamic evolution of the Tethys realm. The consumption of a Neotethys oceanic branch at the Mesozoic-Cenozoic boundary welded the Central Anatolian Crystalline Complex in central Turkey and the Anatolide-Tauride Block in ...

Geochemically unravelling the sedimentary components of Archaean metasediments from Western Australia

open access: yes, 1996
Major and trace elements of metasediments of the granulite facies Narryer and the amphibolite facies Jack Hills metasediments have been used to devise plots which enable the original sedimentary components of these rocks to be unravelled, despite their ...
