Melt inclusions in migmatites and granulites [PDF]

open access: yesJournal of the Virtual Explorer, 2011
Important advances have been made during the last 15 years in the study of melt inclusions in minerals from migmatites and granulites. Pioneer work on high temperature metapelitic anatectic enclaves in peraluminous dacites from SE Spain has shown that droplets of granitic melt can be trapped by minerals growing during incongruent melting reactions, and

Integrated Geophysical Imaging Reveals the Origin and Pathways of Mantle‐Derived CO2 Beneath the Tangra Yumco Rift, Central Tibet

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...

Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: Magnetic anomalies and metamorphic boundaries in the southern Nagssugtoqidian orogen, West Greenland [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2006
Within the southern Nagssugtoqidian orogen in West Greenland metamorphic terrains of both Archaean and Palaeoproterozoic ages occur with metamorphic grade varying from low amphibolites facies to granulite facies. The determination of the relative ages of

Melt Reintegration Modelling: Testing against a Subsolidus Reference Assemblage

open access: yesGeosciences, 2017
Phase equilibria modelling incorporating melt reintegration offers a methodology to create hypothetical rock compositions that may have existed prior to melt loss, allowing the potential prograde evolution of rocks to be explored.

Formation of the Xigaze Metamorphic Sole under Tibetan continental lithosphere reveals generic characteristics of subduction initiation

open access: yesCommunications Earth & Environment, 2023
Metamorphic soles found under allochthonous oceanic lithosphere, or ophiolites, are interpreted as derived from lower plate oceanic crust material accreted to upper plate mantle during intraoceanic subduction initiation.

Transient Porosity During Fluid‐Mineral Interaction, Part 2: Reconstruction Using Generative AI

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Quantifying fluid–rock interactions within the lithosphere is vital for both geological processes and applications such as CO2 ${\text{CO}}_{2}$ storage and geothermal energy development. Mineral replacement reactions generate transient pore networks that enhance fluid flow, yet many pores become isolated once reactions are completed, reducing

Uranium, rare metals, and granulite-facies metamorphism

open access: yes, 2014
International audienceAbstract During granulite-facies metamorphism of metasedimentary rocks by the infiltration of carbonic fluids, the disappearance of hydrated minerals leads to the liberation of aqueous fluids. These fluids are strongly enriched in F

Thermo-tectonic evolution of the Neoarchaean Southern Marginal Zone of the Limpopo granulite Complex (South Africa)

open access: yes, 2023
Combined geophysical, structural geological, metamorphic, geochronological, and stable isotope information is employed to elucidate the Neoarchaean thermo-tectonic evolution of the Southern Marginal Zone (SMZ) within the Limpopo Complex (South Africa ...
