Sažetak
Mesihovina-Rakitno bauxitebearing sedimentary basin in Western Herzegovina are presented. Region with carbonate and clastic hangingwalls as well as those without overlying sediments have been studied. Ii was established that the expression and number of the indicators depend size as well as on character and thickness of hangingwall sediments. The morphological indicators are expressed as a particular relief forms situated right above the deposits or nearby and are a consequence of geological relations and exodynamic processes. The numerous geological indicators resulted from complex geological events. The most important are: preore structural relations, the formation of paleorelief, peculiar way of hangingwall rocks sedimentation, lithification processes and the formation of the recent structural pattern. It has been observed that particular indicators sould be recognized within a relatively thick succession of the overlying sediments which is of the great importance in the exploration of bauxite deposits. In effort to establish certain geomorfological and geological indicators of potential bauxite existence, in small and great depth, we have been governed by numerous relevant ideas concerning the geomorphological and geological relations of investigated area.For a geomorphological analysis which takes into account geological relations, as a first step it is necessary to establish certain units of common geomorphological characteristics. For the geological analysis as well, togethert with detailed geological maps, it is of crucial importance to possess the knowledge of sediment compostion, chronostratigraphic relations. Together with considerable detailed knowledge of tectonic relations and structural characteristics and conditions of bauxite formation as well, it is possible ti distinguish certain geological units of similar geological pattern. As a rule, by considering the problem in this way the correspondence of distinguished geomorphological and geological units can be observed. Within this frame, every and even the slightest exception from a common pattern of distinguished units is considered as an indicator. The importance of indicators only by themselves is relative. However, clustered in one particular locality, they have already hit the target.
