Reaction‐Driven Development of Fine‐Grained Plagioclase Networks Influences the Rheology of the Crust in the Bergen Arcs, Norway

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT In the middle to lower continental crust, mineral reactions can play a key role in controlling rheological behaviour by generating fine‐grained, mechanically weak domains. In granulite‐facies rocks from Krossøy (Bergen Arcs, Norway), we document how garnet breakdown produced interconnected networks of orthopyroxene + plagioclase ± spinel that ...

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.
