GEOMORPHOLOGICAL ASPECTS OF THE OCCURRENCE OF MOLDAVITES IN THE CENTRAL EUROPE ABSTRACT: In the presented paper, geomorphological aspects of the occurrence od moldavites are evaluated. The origin od moldavites in the Miocene and position of their main finding places in Czechia is described. For studies and documentation of morphology of the surface of moldavites was used the collection of the Faculty od Science at Charles University. Special attention during field geomorphic servey of finding places of moldavites was attend to the localities between settlements Ločenice, Nesměň and Chlum nad Malší. Main features od the natural environment were identified as well as recent changes of landforms caused by prohibited and legal extraction of moldavites. All notable finding places of moldavites in the southern Bohemia are affected by these anthropogenic changes of the landscape. It is discussed that absence of moldavites in some denuded areas of the region where they are occurring can indicate a range of rocks exhumation since the upper Miocene. On the contrary, it is suggested thah morphostratigraphical significance od sporadic findings of moldavites many kilometres from primary localities is limited by a low resistance of the shape and volume of moldavites in relation to fluvial transport. However, very...
