NEW DATA ON DEVONIAN STRATIGRAPHY AND CONODONTS OF KULDZHUKTAU MOUNTAINS, UZBEKISTAN

Abstract

Fundamental revision of geology, sedimentology and biostratigraphy of the Devonian deposits exposed in the Kuldzhuktau Mountains, has been resulted in substational upgrade of the regional lithostratigraphy, including re-definition of the age, boundaries and spatial relationships of the local lithostratigraphical units. The detailed Devonian conodont biozonal scale is elaborated and applied for correlation of the locally developed formations with the regional and international chronostratigraphical scales. The Turkmenkazgan Strata was newly introduced for the Upper Devonian succession of carbonates. It was confirmed that Devonian deposits of the Kuldzhuktau Mountains represent strongly tectonized, dispersed and dismembered remnants of the carbonate platform interior, carbonate platform slope and surrounding basin.
