Trondhjemite Leucosomes Generated by Partial Melting of a Hornblende-gabbro (Alvand plutonic complex, Hamedan, NW Iran) [PDF]

open access: yes, 2021
This work describes the petrogenesis of in situ and in-source trondhjemite leucosomes generated by low-degree partial melting of the Jurassic Cheshmeh-Ghasaban hornblende-gabbros in the northern Alvand batholith (Hamedan, NW Iran). These leucosomes occur

Migmatization of Archean aluminous metasediments from the eastern Beartooth Mountains, Montana, U.S.A. [PDF]

open access: yes, 2004
Geothermobarometry, mineral compositions and textures, and thermodynamic models suggest biotite dehydration melting occurred in the peraluminous rocks of the eastern Beartooth Mountains. These Archean metapelitic migmatites are metatexites and diatexites,

Field and Textural Evidence of Two Migmatization Event in the Sierras de Córdoba, Argentina [PDF]

open access: yes, 2008
In the metamorphic basement of the central eastern Sierra de Comechingones (Sierras Pampeanas of Córdoba, Argentina), two types of migmatites are found: Tala Cruz metatexites and Cañada del Sauce diatexites.

Origin of gold mineralization in the Borden Mine and a new tectonic model for the Kapuskasing Structural Zone, Ontario, Canada [PDF]

open access: yes, 2022
The Kapuskasing Structural Zone (KSZ) containing high–pressure granulites is one of the best exposed mid–to–lower crustal sections in the world. However, the timing and mechanism for its formation/exhumation remain highly controversial.

ボヘミアサンカイナンブLhenice shear zoneニサンスルデイシツヘンマガンノゼンガンカガクソセイ [PDF]

open access: yes, 2017
  Whole rock chemical analysis was carried out for sillimanite-cordierite-biotite-garnet (Sil-Crd-Bt-Grt) gneisses at Ktiš in the Lhenice shear zone of the southern Bohemian Massif, Czech Republic, in order to consider the origin of this rock.

A pespectiva geofísica sobre a zona de interferência estrutural entre os cinturões de dobramento neoproterozóicos Brasília e Ribeira no Gondwana Oeste [PDF]

open access: yes, 2017
The Brasília and Ribeira fold belts have been established in south-southwestern São Francisco Craton during the Brasiliano-Pan African orogeny (0.9-0.5 Ga - Tonian to Cambrian), and played an important role in West Gondwana continent assembly. The region

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

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.

Hot lherzolite exhumation, UHT migmatite formation, and acid volcanism driven by Miocene rollback of the Banda Arc, eastern Indonesia [PDF]

open access: yes, 2017
The northern Banda Arc, eastern Indonesia, exposes upper mantle/lower crustal complexes comprising lherzolites and granulite facies migmatites of the ‘Kobipoto Complex’.

Tectonic Evolution of the Prøven Igneous Complex within the Rinkian Fold-Thrust Belt, West Greenland: Investigation using 3D Photogrammetry [PDF]

open access: yes, 2021
The amalgamation of cratons and subduction of oceanic lithosphere in the Paleoproterozoic has formed linear orogenic belts worldwide, such as the little studied Rinkian fold-thrust belt on the west coast of Greenland.
