NEW DATA ON STRUCTURE, COMPOSITION, AND REGIONAL METAMORPHISM OF THE TSAKHKUNYATS AND AKHUM-ASRIKCHAI MASSIFS, THE LESSER CAUCASUS

Abstract

The nappe structure of the Pre-Alpine basement of the Caucasus was established based on identification of large tectonic nappes within the Greater Caucasus and Dzirul and Loksk crystalline massifs. Geological data also point to the thrust–sheet (nappe) structure of the Pre-Alpine basement of the Zakhkunyats and Akhum–Asrikchai massifs of the Lesser Caucasus.
