Tectonic Setting and Evolution of Anatectic Melt Composition During Prograde Metamorphism up to UHT Metamorphism: Constraints From P–T–t–Melting Path From Rundvågshetta, Lützow–Holm Complex, East Antarctica

Journal of Metamorphic Geology, Volume 43, Issue 5, Page 467-495, June 2025.
ABSTRACT The pressure–temperature–time (P–T–t) evolution of a metapelitic ultrahigh‐temperature (UHT) granulite from Rundvågshetta (Lützow–Holm Complex, East Antarctica) and chemical evolution of partial melt during the prograde metamorphism up to UHT metamorphism are studied in detail.

Thermokinematic evolution of the Annapurna-Dhaulagiri Himalaya, central Nepal: The composite orogenic system [PDF]

, 2016
The Himalayan orogen represents a ‘‘Composite Orogenic System’’ in which channel flow, wedge extrusion, and thrust stacking operate in separate ‘‘Orogenic Domains’’ with distinct rheologies and crustal positions.

Rift‐Related Low‐Pressure–High‐Temperature Granulite Facies Metamorphism Generates Widespread Peraluminous Crustal Melts: Evidence From the Early Jurassic Mexican Crust

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract High heat fluxes occurring in rift settings are expected to generate partially melted low‐pressure–high‐temperature granulites (LP–HTG). Therefore, studying these rocks can offer valuable insights into crustal reworking during extension. However, our interpretations are limited by the rarity of LP–HTG in the metamorphic record.

Multi‐Stage Growth of Kyanite in Migmatites Interpreted by Integrating Forward Thermodynamic Modelling and Trace Element Signature

Journal of Metamorphic Geology, Volume 43, Issue 4, Page 315-339, May 2025.
ABSTRACT Trace element zoning in kyanite can retain information about its growth history, particularly in anatectic metapelites. There, kyanite can grow (i) at sub‐solidus conditions through metamorphic reactions involving other aluminous phases as reactants, (ii) through muscovite dehydration melting reactions, and (iii) during cooling and melt ...

A zircon petrochronologic view on granitoids and continental evolution

Earth and Planetary Science Letters, 2020
Abstract Temporal trends in granitoid chemistry and thermometry constrain major global changes in magmatism, tectonism or crustal thickness in the continents. Our study relies on zircon geochronology and trace element geochemistry on four new detrital rocks (two modern sediments and two Archean metasedimentary rocks) and a global compilation of ...

Petrochronology of High‐Pressure Veins Reveals the Evolution of Fluid Sources in Subducted Oceanic Crust (Rocciavrè Eclogites, W. Alps)

Journal of Metamorphic Geology, Volume 43, Issue 3, Page 225-256, April 2025.
ABSTRACT The Rocciavrè massif is a large eclogitized ophiolitic fragment exposed in the Western Alps (Piemonte, Italy) exhibiting an almost complete sequence of the subducted Liguro‐Piemont lithosphere. Raman spectroscopy on carbonaceous material in metasediments from Rocciavrè and the juxtaposed Orsiera massif indicates maximum temperatures in the ...

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.

Metamorphic modeling and petrochronology of metapelitic rocks from the Luminárias Nappe, southern Brasília belt (SE Brazil)

Brazilian Journal of Geology
The Luminárias Nappe was formed in the agglutination of West Gondwana. A high-pressure metamorphic gradient oblique to the geological contacts is recorded in metapelitic rocks from this Nappe.

The magmatic–hydrothermal transition record in zircon: implications for zircon texture, composition and rare-metal granite dating (Beauvoir granite, French Massif Central) [PDF]

European Journal of Mineralogy
Zircon petrochronology is widely used to quantify the age and duration of magma emplacement and differentiation. However, in highly differentiated magmas, such as those forming rare-metal granites, zircon may form at the magmatic–hydrothermal transition,
