Age of the High-Temperature Gneiss Core of the Central Caucasus

摘要

Different pre-Mesozoic formations dominated by metamorphic complexes are widespread in the mountainous Central Caucasus. Knowledge of their ages is essential for interpretation of the pre-Mesozoic structure, evolution, and geodynamics of the Crimean-Caucasian segment at the southern active margin of Eurasia. These issues are still highly debatable. It is widely accepted that metamorphic rocks are of Proterozoic age in all zones of the Central Caucasus.
