THE IMPACT OF GLACIAL PROCESS ON THE EVOLUTION OF POLJES IN MONTENEGRO

Abstract

Poljes of Montenegro are formed within the Dinaric mountain system. These poljes are usually small surface, only several square kilometers. They are located at different altitudes from 6 to 1305 m a. s. l. The glacial process had direct and indirect impact in the development of poljes. The direct impact reflected in the fact that during the strongest glaciations, the absolute dating was established that occurred during the MIS 12, when many glaciers descended right into poljes, where they are deposited large amount of moraine material. Because of this some part of poljes were covered by moraines. During the Later glacial phase (MIS 6) scope of glaciations was significantly lower, and glaciers were not descended into poljes. The indirect impact reflected in the strength of river transport, which is increased by melting of glaciers. The consequence of increased power river was transporting glacial material, which infilling, uplifting and leveling bottom of poljes. All of this had a significant impact on water circulation in the karst. The recent period represents the end of transport of glacial material, dominance of karst processes and plunge of river flows.
