Constraints on the Feasibility of Ferrovolcanism on Asteroid 16 Psyche

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.
Abstract Asteroid 16 Psyche's surface appears to be highly metallic, but its bulk density suggests a silicate‐rich interior. Ferrovolcanism has been suggested to explain how a silicate‐rich body could develop a metallic surface. This requires trapping of light elements bearing iron‐rich metallic melt in a core solidifying from the outside inwards.

A Gravity Study of the Crustal Structure Beneath the Young Amagmatic Rukwa‐Tanganyika Rift Zone

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Rukwa‐Tanganyika Rift Zone (RTRZ), experiencing multiphase rifting, forms the nonvolcanic southern part of the Western Branch of the East African Rift. We investigate the crustal structure beneath the RTRZ to understand how strain migrates beneath multiphase rifts.

Ductile Crustal Flow Facilitates Intraplate Volcanism: Seismic Evidence From Tengchong, China

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The mechanisms and processes driving intraplate volcanism remain incompletely understood despite significant advances in recent decades. Here, we use high‐resolution multiparameter full‐waveform inversion to image the three‐dimensional seismic structure beneath the Tengchong volcanic region in southwestern China. Our model reveals a pronounced

Technical changes in the glaze composition of tin‐glazed sculptures by Benedetto Buglioni c. 1490–1510

Archaeometry, Volume 67, Issue 4, Page 984-1000, August 2025.
Abstract During the 15th and into the mid‐16th centuries, tin‐glazed terracotta sculptures were celebrated for their luminous colours, perceived durability, and technical ingenuity of the novel medium. Although in high demand, the supply of these pieces was restricted because of the secrecy of the recipes used by the pioneers of the technique on the ...

The Distribution of Major and Trace Elements Across a Garnet Population From the Kalak Nappe Complex (Finnmark, Scandinavian Caledonides): Evidence for Size‐Dependent Growth and Compositional Equilibration in the Garnet Zone

Journal of Metamorphic Geology, Volume 43, Issue 6, Page 613-640, August 2025.
ABSTRACT A garnet population from the lower Kalak Nappe Complex in Finnmark (Arctic Norway) was characterized using high‐resolution X‐ray micro‐computed tomography, electron probe micro‐analysis and laser ablation inductively coupled plasma mass spectrometry mapping to assess the extent of compositional equilibration and the controlling crystallization
