THRUSTS, OLISTOSTROMES AND MELANGE OF THE DZHIDA CALEDONIDE ZONE IN BURYATIA

The Dzhida Caledonide zone in Buryatia and its framing is a system of gently and high dipping tectonic plates of Riphean metamorphic complex es overthrust on the Caledonian terrain of the Dhida zone and Mesozoic complex of Malo-Khamar-Daban volcanic structure. The process of thrus ting was accompanied with the formation of olistostrome, then with the formation of isoclinal folds, structures of plastic current and melan ge, tectonization of olistostrome, protrusive injection of ultrabasite and calcareous tectonic erratic masses, and it was conditioned by the southward movement of the Angara-Anabar block of the Siberian craton (in the present coordinates).
