Magmatic and tectonic history of Jurassic ophiolites and associated granitoids from the South Apuseni Mountains (Romania)

open access: yes, 2016
The Jurassic ophiolites in the South Apuseni Mountains represent remnants of the Neotethys Ocean and belong to the East Vardar ophiolites that contain ophiolite fragments as well as granitoids and volcanics with island-arc affinity. New U–Pb zircon ages,

Overlapping Sr-Nd-Hf-O isotopic compositions in Permian mafic enclaves and host granitoids in Alxa Block, NW China: Evidence for crust-mantle interaction and implications for the generation of silicic igneous provinces

open access: yes, 2015
In general, the mantle provides heat and/or material for the generation of the silicic igneous provinces (SIPs). The rarity of mafic microgranular enclaves (MMEs), however, hampers understanding of the mantle's role in generating SIPs and the process of ...

K-Ar ages of the La Alberca-Béjar granitoids (Spanish Central System)

open access: yes, 1996
Late-kynematic granitoids of the Central Iberian Zone (Iberian Variscan Massif) outecrop in the La Alberca-Bejar region (Salamanca, Spain). The granitoids postdate the regional second variscan deformation phase.

Eocene Kashmar granitoids (NE Iran): petrogenetic constraints from U-Pb zircon geochronology and isotope geochemistry

open access: yes
Kashmar granitoids outcrop for ~100 km along the south flank of the Sabzevar ophiolite (NE Iran) and consist of granodiorite and monzogranite along with subordinate quartz monzonite, syenogranite and aplitic dikes.
