[1] Granitoid magmatic sheets emplaced syntectonically during growth of the Orlica-Śnieżnik mantled gneiss dome (Central Sudetes, European Variscan belt) were examined by means of structural geology, quartz, and anisotropy of magnetic susceptibility (AMS) fabric studies. Magmatic emplacement was localized along the eastern transpressive

Structural, petrological and textural evidence indicates that the dynamothermal contact originally evolved as a subhorizontal ductile shear zone during juxtaposition of the greenstone pile with granitoid gneiss and that its formation preceded regional folding, greenschist facies overprinting and granitoid intrusion which occurred at about 2700 Ma. Granite Gneiss. Two ages were determined in the Vumba granitoids, namely, the 3385±255 Ma and the 2527±632 Ma (Manuel, 1992) north and south of the Manica greenstone belt respectively. The biotite bearing granitoid gneisses are of Proterozoic age and are grouped into the Messica Granite Gneiss. Granitoid, granitoidní nebo granitická hornina je souborné označení pro kyselé magmatické horniny od alkalických granitů přes granodiorit po tonality. Tyto horniny mezi sebou v přírodě běžně prostupují a jsou si natolik podobné, že bez mikroskopické analýzy je prakticky nemožné je rozlišit. Termín granitoid zavedl v roce 1925 ruský geolog Fjodor Levinson-Lessing.

SHRIMP U-Pb zircon and titanite dating have been used to constrain the timing of mid- to lower-crustal metamorphism (∼650-700°C and 8-11 kbar) and syn-kinematic melting in the granitoid gneiss-dominated terrane south of the Barberton greenstone belt, S Granitoid gneiss is a variety of metamorphic gneiss that appears to have bands of black and white minerals such as feldspar and mica.
