Polyphase Metamorphism of the Northern Rae Craton (Baffin Island, Arctic Canada) and Trace Element Behaviour in Monazite: Insights From Phase Equilibria Modelling and Geochronology

Journal of Metamorphic Geology, Volume 43, Issue 3, Page 287-314, April 2025.
ABSTRACT Integrated field mapping, phase equilibria modelling and in situ U–Pb monazite geochronology from the northern margin of the Rae craton on Baffin Island document three metamorphic events during the Neoarchean to the middle Paleoproterozoic.

Large Contact Aureole Overprinting the Ryoke Regional Metamorphic Zoning: Insights From the Takato–Komagane Area, Central Japan

Island Arc, Volume 34, Issue 1, January/December 2025.
ABSTRACT The Ryoke metamorphic belt records the conditions of the middle–upper crust during Cretaceous crustal deformation and magmatism. To understand the development and evolution of the middle–upper crust, it is important to investigate the thermal structure of the Ryoke metamorphic belt.

Carboniferous Barrovian to Permian Buchan‐type metamorphic cycles in the Mongolian Altai Zone: Implication for pressure cycles in accretionary orogens

Journal of Metamorphic Geology, Volume 42, Issue 7, Page 979-1033, September 2024.
Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, the timing and link between these cycles are not clear, and their causes are debated. In order to contribute to the understanding of Barrovian‐ to Buchan‐type evolution of the accretionary wedges, we

The fate of accessory minerals and key trace elements during anatexis and magma extraction [PDF]

, 2020
This work was financially supported by ARC grant DP110102543.Granite genesis and crustal evolution are closely associated with partial melting in the lower or middle crust and extraction of granite magmas to upper levels.
