A methodological approach to the thermochronology of the Winnebach migmatite

open access: yes, 2017
Der Winnebach Migmatit ist ein polymetamorpher Migmatitkörper im Ötztal Kom- plex (Ostalpen, Österreich). Die partielle Anatexis hat ein Kambro-ordovizisches Al- ter.

Petrology and Geochemistry of an Archean Migmatite Terrain, Favourable Lake Area, Northwest Ontario [PDF]

open access: yes, 1979
The "F-Zone" is part of a migmatitic, radiometrically anomalous belt which forms the contact between a large granitic batholith and a region of homogeneous diatexite.

Orogenic Eclogites Record Relative Magnitude of Deep Crustal Flow and Extent of Migmatite-Eclogite Interaction

open access: yes, 2021
International audienceRefractory rocks exposed in exhumed orogens have potential to preserve a record of high-pressure (HP) petrogenesis that is commonly obliterated in quartzofeldspathic rocks during high-temperature decompression. In the Montagne Noire

The Benta Migmatite Complex: petrology of two important localities

open access: yes, 1971
The general geology, petrography, and petrogenesis of the Benta Migmatite rocks are described and discussed in the light of two well-exposed sections near Benta, Pahang. The rock which has previously been referred to as " flow-banded syenite" is shown to

Orogenic eclogites record relative magnitude of deep crustal flow and extent of migmatite-eclogite interaction

open access: yes, 2022
International audienceIn exhumed orogens, refractory mafic rocks have the potential to preserve a record of petrogenesis and high-pressure (HP) metamorphism that is commonly obliterated in quartzofeldspathic rocks owing to re-equilibration at high ...

Geochemical Characterisation of Anatexite within High Grade Migmatite Complex Terrain from Ogbomoso, Southwest of the Nigerian Precambrian Basement Complex

open access: yes, 2019
Migmatite rocks are complex rocks largely due to the degree of partial melting and nature of parent rocks of this rock type. Partial melting or anatexis yield metatexite and diatexite components with variable mineralogical and chemical compositions.
