Metamorphic-granitogenic rocks of the basement complex of the Great Hungarian Plain, Eastern-Hungary
The metamorphic-granitogenic rocks of the Great Hungarian Plain showing a SW—NE trend have been uncovered by hundreds of hydrocarbon exploring boreholes. The central part is composed of polymetamorphic biotite-plagioclase gneisses, mica schists, amphibolites which gradually pass into migmatites and/...

| 520 | 3 | |a The metamorphic-granitogenic rocks of the Great Hungarian Plain showing a SW—NE trend have been uncovered by hundreds of hydrocarbon exploring boreholes. The central part is composed of polymetamorphic biotite-plagioclase gneisses, mica schists, amphibolites which gradually pass into migmatites and/or diatexites of granodioritic composition in the marginal parts of the deeply buried ranges involved. The polymetamorphic rocks are intersected by younger granites of medium grain-size. In some boreholes in the southern part of the Great Hungarian Plain micaquarzites, chlorite schists belonging to the greenschist facies as well as staurolite-mica-schists belonging to the almandine-amphibolite facies have been found, all of them hit by a single metamorphism only. The formation of the metamorphic-granitogenic rocks is a result of three tectono-metamorphic cycles. The first one caused a regional metamorphism of the Proterozoic source rocks into the amphibolite facies and resulted in a synkinematic granodiorite formation. A regressiv metamorphism took place in the second cycle manifesting itself by milonitization and diaphtoresis along narrow zones. The regressive metamorphism resulted in mineral associations of the greenschist facies. These rocks show a limited regional extension until now. The final cycle caused some metasomatic transformations of considerable intensity as well, forming late kinematic granites. | |
