GEOLOGICAL PALEOCEANOGRAPHY OF FORE-DOBRUDJA SEGMENT OF TETHYS IN DEVONIAN
Geological-paleooceanographic situations of Devonian sedimentation within Fore-Dobrudja segment of Paleotethys have been con- sidered. It has been shown that subsidence and cold climate caused terrigenous sedimentation predominance in Early Devonian with local progress of organogenic carbonates. Ascendant tectonic movements and aridization of climate in Middle - Late Devonian caused sulphate-carbonate depositionsof cyclic structure in half-isolated basins, fixed by changes of relative level of the ocean.
