Melt inclusions in migmatites and granulites [PDF]
Journal 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

Structural evolution of the Vuotso area, Finnish Lapland [PDF]
Bulletin of the Geological Society of Finland, 2003 The Vuotso area is structurally interesting because the fold interference pattern in rocks of central Lapland changes into thrust-related foliation of the Lapland Granulite Belt.

BSGF - Earth Sciences Bulletin, 2021 Large uncertainties remain about the architecture, timing and role of the structures responsible for high degrees of crustal thinning and the exhumation of mid-crustal granulites in the Pyrenean and Biscay rift systems.

Contrasting appinites, vaugnerites and related granitoids from the NW Iberian Massif: insight into mantle and crustal sources [PDF]
European Journal of Mineralogy, 2023 Post-collisional Mg–K-rich mafic rocks with associated granitoids appear regularly in most orogens. They are relevant to evaluate the mantle role in the genesis of granitoids and thereby of the continental crust itself. The most characteristic Mg–K mafic

Литосфера, 2017 The article discusses the problem of the nature of high-alumina garnet granulites from Sutam River (Aldan Shield). The studies revealed that the majority of detrital grains have U-Pb age of up to 1.92 Ga; however the zircon grain of 3.94 Ga has been for ...

The 3.5 Ga Siurua trondhjemite gneiss in the Archaean Pudasjärvi Granulite Belt, northern Finland [PDF]
Bulletin of the Geological Society of Finland, 2003 In the Archaean Pudasjärvi Complex the pyroxene-bearing rocks are considered to form a belt, the Pudasjärvi Granulite Belt (PGB). The major rock types of the PGB are meta-igneous mafic and felsic granulites, and trondhjemite gneisses Red alaskites, white

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part II: Isotopic dating [PDF]
Bulletin of the Geological Society of Finland, 2006 The migmatitic metapelites of the Lapland granulite belt (LGB) in the NE part of the Fennoscandian Shield represent an arc-related greywacke basin metamorphosed in the granulite facies. Detrital zircons from migmatitic metapelites are derived from 1.94 −

Metamorphic history and geodynamic significance of the Early Cretaceous Sabzevar granulites (Sabzevar structural zone, NE Iran) [PDF]
Solid Earth, 2011 The Iranian ophiolites are part of the vast orogenic suture zones that mark the Alpine-Himalayan convergence zone. Few petrological and geochronological data are available from these ophiolitic domains, hampering a full assessment of the timing and ...

Are granites and granulites consanguineous?
, 2015 © 2015 Geological Society of America. An important question in petrology is whether the production of granite magma in orogens is a closed-system process with respect to mass input from the mantle.
