Preliminary scope of work

Hlavní náplní disertační práce bude podrobná strukturní analýza vybraných deformačních zón v oblasti východoafrického orogenu (Etiopie), mikrostrukturní analýza deformačních struktur, PT-modelování vývoje smykových zón, interpretace kinematické a deformační historie, PT-modelování vývoje smykových zón, analýza kinematických a deformačních zón. celkově s obecnými důsledky pro konečnou architekturu orogenních pásů.

Preliminary scope of work in English

The main scope of disseration will include a detailed structural analysis of selected deformation zones in the area of the East African orogen (Ethiopia), microstructural analysis of deformation structures, PT-modelling of the development of shear zones, interpretation of kinematic and deformation history, overall with general implications for the final architecture of orogenic belts.
