Summary: The project is designed to investigate the relationship between the emersion phases (subaerial exposure phases) and the bauxite and terra rossa deposits in the Dinarides. The research is closely related to the development of the carbonate platforms (Triassic to Tertiary in age) in the Dinarides. Concerning the fact that bauxite and terra rossa are closely related from the genetic viewpoint, special attention will be given to the fosill and recent terra rossa deposits and their parent materials. The effects of paleogeography, duration of subaerial exposure phases erosion and tectonics to the mineralogical and chemical composition of bauxites, their parent material and geotectonic position will be evaluated.

Keywords: Dinarides, Carbonate platform, bauxites, Terra rossa, parent materials, paleogeography, paleorelief, paleosols, mercury, rare earth elements (REE), genesis

Research goals: The main task of the project is to investigate mineralogical and chemical characteristics of the bauxite and terra rossa deposits and to establish their mutual genetic relationships. Our intention is also to establish possible relationship between parent materials of some bauxite horizons and volcanic activity. The scope of investigation of recent and fosil terra rossa is to establish genesis of these materials and to define their micromorphological characteristics. The research of sedimentological and petrological features related to the carbonate platform is designed to obtain relevant facts on biofacies and litofacies characteristics of sedimentary rocks.Investigation of rhytmic and cyclic sedimentation, environmental aspects of sedimentation, sea-level changes and tectonics are also performed. As the result of all the factors mentioned shorter or longer emersion phases occured with the formation of bauxites. The results achieved so far have been published in major number of publications. They are also included in the reports of the international project IGCP-287 and will be published in a special publication of an important world publisher.
