Rapakivi K‐Feldspar Megacrysts in Monzogranitic Porphyry: Evidence for Magma Recharge and Mush Rejuvenation

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The formation, storage, and evolution of granitic magmas are fundamental processes driving the growth of continental crust. While traditionally attributed to crystal fractionation in high‐melt fraction magma chambers, the model invoking low‐melt fraction crystal mushes has gained wide acceptance.

Characteristics of ∼40 Ma Mafic Rocks in North Tibet and Their Tectonic Implications

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Several magmatic belts are present in the Tibetan Plateau. Among these, the Qiangtang magmatic belt in North Tibet remains elusive. In particular, the petrogenesis, magma source, and tectonic implications of the ultramafic to mafic rocks in the North Qiangtang area are underinvestigated due to their sparsity and remoteness.

Thermal Reactions of Smectite Minerals at Earthquake Timescales

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Frictional heating causes a transient temperature rise in fault zones during earthquakes that leads to metamorphic reactions within the fault rocks. The products of these reactions provide potential evidence of earthquakes in both the outcrop and drill core. Clay minerals such as smectites are commonly found in faults.

Automatic Analysis of Hydroacoustic Signals Related to the Activity of the Fani Maoré Submarine Volcano

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Due to the properties of sound propagation underwater, including the existence of the SOFAR channel, sounds in the ocean can propagate over large distances with little attenuation. This makes passive acoustics a relevant method for monitoring natural events such as ice calving, earthquakes, and underwater volcanic eruptions.
