Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Prograde zircon growth in migmatites

Journal of Metamorphic Geology, 2023
AbstractEmpirical studies of zircon in migmatites document features compatible with growth during heating at suprasolidus conditions. However, numerical modelling of zircon behaviour suggests that suprasolidus zircon is expected to grow only during cooling and melt crystallization.

Complementary geophysical, geomorphometric and pedological approaches for characterizing shallow and deep subsurface materials in a colluvial‐alluvial plain in Atlantic rainforest

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
This study combines GPR, 2D ERT and UAV‐derived terrain models to characterize sediment variability in a colluvial‐alluvial plain. GPR identified sandy lenses and clay‐rich layers, while ERT revealed deeper conductive and resistive zones, including a gneissic basement.

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 ...

Exploring the relationships between shear zones and granites: field and microstructural data for contrasting case studies of the Borborema Province (NE Brazil)

Geologia USP. Série Científica, 2021
We explore meso- and microstructural features of granites closely related to strike-slip shear zones in the Borborema Province, NE Brazil. The Riacho do Icó Stock is an en-cornue intrusion aged at ca. 607 Ma.
