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.

Subduction‐Driven Reworking of Craton and Accretionary Orogen: Evidence From Integrated Geophysical Imaging in Western North China Craton

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Observations and interpreted mechanisms for the reworking of Precambrian cratons and accretionary orogens have significant relevance in understanding the history and evolution of continental lithosphere. Here we investigate the Precambrian basement and lithospheric architecture of the western North China craton (NCC) through the integration of

Reactive Melt Flow in the Continental Arc Root: Insights for the Transition From Gabbronorite to Garnet Granulite in the Central Qilian Belt, NE Tibet

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Understanding reactive melt flow is crucial for advancing our knowledge of crustal differentiation; however, the mechanisms governing melt migration remain debated, particularly in deep magmatic arc environments. A composite sample from the Central Qilian continental arc, NE Tibet, preserves the transition from hornblende gabbronorite to ...

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

Journal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

Study of Migmatization and Leucocrate granite formation processes in the Tuyserkan area, Hamedan

Journal of Economic Geology, 2020
Introduction Partial melting is an appropriate correlation process between metamorphism and magmatism which plays a key role in the development of migmatites, granulites and S-type granites during crust evolution (Kriegsman, 2001; Alvarez-Valero and ...

METALLOGENY OF SOUTH TISIA - MOSLAVAČKA MT., PSUNJ, PAPUK AND KRNDIJA

Rudarsko-geološko-naftni Zbornik, 2013
Core of the Moslavačka Mt. is built of S-type granite and granodiorite, wrapped up in migmatites. Outer zone is represented with metamorphites of amphibolite facies. The Moslavačka Mt.

Migmatites, Melting, and Metamorphism

Eos, Transactions American Geophysical Union, 1985
This is a praiseworthy collection of papers that illustrates the great range of interests necessary to understand migmatite genesis. The strength of the collection lies in its broad approach to the study of migmatites and its emphasis on the link between “igneous” and “metamorphic” processes.
