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 ...

Santonian-Campanian marly and biodetritic facies in the Púchov Formation in the Orava sector of the Pieniny Klippen Belt (Slovakia)

Mineralia Slovaca
The Pieniny Klippen Belt is characterized by the block-in-matrix fabric with Jurassic to Lower Cretaceous rigid klippen embedded in less competent Upper Cretaceous flysch and marlstone matrix.

3D Petro‐Structural Evolution of the High Pressure‐Low Temperature Phyllite‐Quartzite Nappe Pile in Southern Peloponnese, Greece

Tectonics, Volume 44, Issue 12, December 2025.
Abstract Tectonic underplating of high‐pressure/low‐temperature (HP‐LT) tectonic slices is a key mechanism in crustal growth at convergent margins. Yet, the processes controlling the geometry, depth and sequence of underplating events remain poorly constrained.

Alternative interpretation of the Bystrica Unit in Klanečnica KLK-1 borehole (Magura Nappe)

Mineralia Slovaca
In 1986, the KLK-1 (Klanečnica) borehole was drilled northwest of Moravské Lieskové as part of a regional oil and gas exploration programme. The well reached a total depth of 662 m and was intended to verify the occurrence and potential accumulation of ...

Thermal properties of orogenic flysch and schist, Rakaia Terrane, Torlesse Composite Terrane, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 831-847, December 2025.
ABSTRACT Voluminous, deformed, and variably metamorphosed argillite and greywacke sediments (flysch) are common orogenic rock types. Knowledge of their physical properties is required to make tectonic and geothermal models of modern and ancient plate boundaries.

Geological structure and evolution of the Pieniny Klippen Belt to the east of the Dunajec River : a new approach (Western Outer Carpathians, Poland)

, 2014
The area studied, known as the Małe (Little) Pieniny Mts., belongs to the Pieniny Klippen Belt (PKB), a suture zone that separates the Central Carpathians from the Outer Carpathian accretionary wedge. Along its northern boundary the PKB is separated from

Predicting climate-induced changes in groundwater resources on the basis of hydrogeological model research: Case study of the Carpathian flysch belt

Episodes, 2013
The level of water in aquifers depends mostly on precipitation. However, recent research has shown that greater annual rainfall values do not necessarily trigger off an automatic increase in groundwater recharge. The lowering of the water table may result not only from lower precipitation, but also from intensification in evaporation and a decreased ...

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

The Middle Jurassic succession in the central sector of the Pieniny Klippen Belt (Sprzycne Creek): implications for the timing of the Czorsztyn Ridge development

Geologica Carpathica, 2015
In this study, we revisit the stratigraphic age and discuss sedimentary characteristics of the lower Middle Jurassic turbidite deposits (“black flysch”) of the Szlachtowa Formation, as well as the under- and overlying members of the Sprzycne Creek ...
