Geodynamic evolution and post-collisional magmatic activity in the Arabian-Nubian Shield (East African Orogeny) and southwestern Moldanubian Zone (Central European Variscides)
Název práce v češtině:
Geodynamický vývoj a postkolizní magmatické aktivitě v jednotce Arabsko-Nubijského štítu (Východoafrické orogenní pásmo) a severozápadní části Moldanubika (Středoevropské variscidy)
Název v anglickém jazyce:
Geodynamic evolution and post-collisional magmatic activity in the Arabian-Nubian Shield (East African Orogeny) and southwestern Moldanubian Zone (Central European Variscides)
Klíčová slova:
East African Orogeny, Arabian-Nubian Shield, European Variscides, Bohemian Massif, Moldanubian Zone, U-Pb dating, Anisotropy of Magnetic susceptibility, P-T modelling
Klíčová slova anglicky:
Východoafrický orogen, Arabsko-nubijský štít, evropské variscidy, Český masív, Moldanubiku, U-Pb datování, anizotropie magnetické susceptibility, P-T modelování
The Ph.D. research examines the late-orogenic evolution and post-collisional magmatic activity in two different collisional orogenic belts – southwestern Moldanubian Zone in the Central European Variscides and Tokar-Barka terrane in southern Arabian-Nubian Shield (East African Orogeny). The geological pattern of the southwestern Moldanubian Zone is characterized by late-orogenic HT anatexis and emplacement of postcollisional granites dated 330 to 315 Ma. The Tokar-Barka terrane exposed in Ethiopia is formed by medium- to low-grade metamorphic and plutonic rock assemblages newly dated at 765 to 618 Ma. Based on new U–Pb zircon data, Anisotropy of Magnetic Susceptibility, thermobarometric P-T calculations coupled with field structural analysis overall geodynamic evolution will contribute to infer the geodynamic evolution that operated in the later stages of compressional type of orogeny.
