In recent years, considerable progress has been made on the study of Mo isotopes in high-temperature geological processes. However, it is still controversial whether isotope fractionation occurs during magmatic differentiation. Here we reassess effect magma differentiation using published data conjunction with our new analysis well-characterized I-type granitoids and their enclosed mafic enclav...

The presented studies are aimed to determine the formation patterns of gold-rare metal mineralization within one most inaccessible Arctic islands Russian Federation, Bolshevik Island Severnaya Zemlya archipela-go. relevance work is determined by high probability discovering a significant in terms reserves deposit, which proved many researchers on example known large deposits be typical feature ...

The area of study is located 120 Km north-east of Shahrood city. In terms of structure and geological classification, this area is located in the northern part of central Iran zone. Granitoids of Troud ranging from monzonite to granite. The main minerals of granitoids are quartz, plagioclase, and orthose. The accessory minerals are biotite, hornblende, sphene, and opaque minerals. Various textu...

Oligo-Miocene Bagh-e-Khoshk granitoid stock is intruded into the Eocene volcanic rocks in the southeastern part of the Urumieh-Dukhtar Magmatic assemblage in Iran. The granitoids are mainly consisting of diorite, quartz diorite and granodioritic rock types. They are metaluminous to slightly peraluminous, medium to high K calc-alkaline, with SiO2 ranging from 50.2 to 66 wt.%. The majo...

The Sierra de Guasayán (Eastern Sierras Pampeanas, Argentina) is formed by low to medium grade metamorphic rocks intruded Cambrian metaluminous (La Soledad quartz-diorite), slightly peraluminous (Guasayán, El Escondido and Martirizado granodiorite plutons), strongly (Alto Bello granodiorite) granitoids of the Pampean magmatic arc. Chemical compositions amphibole, plagioclase, biotite, titanite ...

Early Jurassic U-Pb age is obtained for both foliated and undeformed granites on Horseshoe Island, Antarctic Peninsula. Some microstructures in the granites/orthogneisses indicate high-temperature greenschist or low- to medium-temperature amphibolite facies deformation conditions. Additionally, a Late Cretaceous yielded gabbro intruding deformed granitoids.
