ABSTRACT This study investigates garnet–clinopyroxene double‐layered coronae in a metagabbronorite from the high‐grade metamorphic Gföhl Unit (Bohemian Massif). The coronae formed at the interfaces between relic magmatic orthopyroxene, still preserved in the cores of the coronae, and the plagioclase‐rich rock matrix.

ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

2021 Alaska earthquake: entropy approach to its precursors and aftershock regimes [PDF]
We have conducted an entropy analysis in Alaska, a seismic-rich region in a subduction zone that exhibits a nontrivial behavior: the subduction arc alters the seismic activity from the eastern zone to the western zone, demonstrating a decrease in ...

The spatial distribution characteristics of Nb–Ta of mafic rocks in subduction zones
High field-strength elements have been regarded as one of the most important discriminations in subduction zone magma. However, the spatial distribution of Nb and Ta in subduction zone-related rocks has been rarely studied; it is still unclear whether ...

Makran Subduction Zone: A Review and Synthesis
This review synthesizes existing research to elucidate the factors driving the distinct tectonic behaviors in the western and eastern Makran subduction zone, focusing on seismic activity, uplift rate, convergence rate, coupling, and subduction angle. The

Pressure, temperature and time constraints on tectonic models for southwestern Sweden [PDF]
In this work, a number of key localities have been investigated in detail in order to provide precise constraints on models for the tectonic evolution of southern Sweden.

Rapid subduction initiation and magmatism in the Western Pacific driven by internal vertical forces
The magmatic progression produced during the initiation of the Izu-Bonin-Marianas subduction zone took place rapidly over 1 million years, but it has been unclear why.

Variations in the crustal structure and strength of plate coupling along the Ryukyu subduction zone
The Ryukyu trench-arc-back arc system is part of the subduction margins of the Philippine Sea plate. Previous studies have indicated that several geophysical and geological characteristics reveal significant variations (including convergent rate ...

Earth's rotation variability triggers explosive eruptions in subduction zones [PDF]
The uneven Earth’s spinning has been reported to affect geological processes, i.e. tectonism, seismicity and volcanism, on a planetary scale. Here, we show that changes of the length of day (LOD) influence eruptive activity at subduction margins ...
