Multi-stage emplacement of the Götemar Pluton, SE Sweden: new evidence inferred from field observations and microfabric analysis, including cathodoluminescence microscopy
The emplacement of the Mesoproterozoic Götemar Pluton into Paleoproterozoic granitoid host rocks of the Transscandinavian Igneous Belt is re-examined by microfabric analysis, including cathodoluminescence microscopy. Field data on the pluton-host rock system are used to strengthen the model. The Götemar Pluton, situated on the Baltic Shield of SE Sweden, is a horizontally zoned tabular structur...

Magma flow within the Tavares pluton, northeastern Brazil: Compositional and thermal convection
Crystallization coupled with gravity removal of depleted interstitial melt has long been recognized as a mechanism of magma differentiation. Similarly, heat released by synplutonic basaltic magma intrusions has long been recognized as capable of driving convection in granite chambers. Direct evidence of these processes has seldom been described in granites. In the Tavares pluton, we mapped a nu...

Toye-Darvar granitoidic pluton is located in southwest of Damghan, in the southern flanke of eastern Alborz structural zone. Despite of its uniform appearance in the field, this pluton is composed of a rock with a wide range of composition including of diorite, monzodiorite, monzonite, quartzmonzonite and granodiorite with monzonite-quartzmonzonite prevalence. Based on the field observations, t...

The Lakhshak pluton, a part of Zahedan-Saravan granitoid belt, is located about 15 km NW of the Zahedan city. The plutonic rocks are granodiorite in composition and are cut by a numerous of microdiorite and dacite dykes. The rocks of Lakhshak pluton consist of plagioclase (oligoclase-andesine), K-feldspar, quartz, biotite, amphibole (pargasite - edenite), sphene, apatite and opaque minerals. In...
