Summary: The project gives the scientifically documented answer to the following dilemma: affiliation to the Variscan or Alpine metallogeny or to the orogenetic remobilization of the ore occurrences and ore deposits spatially connected inside the Palaeozoic of the Dinarides in Croatia, northwestern and central Bosnia. The project try to solve all earlier open scientific problems for the bigger and more important ore deposits: paragenesis, geochemistry, tectonic setting, genetic type, relation to the magmatism, affiliation to the particular magmatic epochs and to the particular phase of the Vilson cycle. The comparison with the other Paleozoic regions in Slovenia, northeastern and southeastern Bosnia and Montenegro gives the conception of the geotectonic evolution and metallogeny of the whole space of the Dinarides. The results of the detailed geochemical investigations of the barite and barite-siderite Hg-tetrahedrite-bearing deposits in the Mid-Bosnian Schist Mountains in comparison with the geotectonic and geochemical characteristics of the almost identical genetical types of Hg-bearing tetrahedrite deposits situated in the Palaeozoic in Brixlegg-Kitzbhel (Tyrol, Austria) and those in the Palaeozoic of Rudnany (Slovakia) makes possible to support the hypothesis of the uniformity of the sedimentation space during the Early and Middle Palaeozoic in the Dinarides and in the Eastern Alps. Owing to the inadequacy of the financial support (state of war) the dating using the potassium/argon, strontium isotopes, lead isotopes methodes have not been utilised. The exact dating is of great significance for the project. Therefore we are interested to extend the project.

Keywords: Dinarides, Croatia, Northwestern and Central Bosnia, Palaeozoic, Ore deposits, Tectonic settings, Genetic types, Isotope study, Fluid inclusions, Microelements, Cronostratigraphy, Metallogenetic epochs.

Research goals: The proposed scientific project should give to the utmost the documented answer to the following dilemma: the ore deposits situated in the Paleozoic of the Dinarides in the frame of Croatia and Bosnia were formed in the course of the Palaeozoic time or they belong partially or completely to the Alpine metallogenic epoch or they are even orogenetically remobilized during the younger metallogenetic cycle. In first phase the goal of the investigation is consacrated to the classification of the ore deposits according to particular phase of the Vilson cycle:(a) hot spot magmatism and intracontinental rifting, (b) ocean floor-spreading, (c) ocean floor subduction, (d) continent-continent-Arc collision, (e) postcollision rifting, (f) Alpine type of remobilisation. In the second phase the goal is chronostratigraphical classification to the (a) Caledonian, (b) Hercynian, (c) Alpine metallogenetic epochs, and (d) Alpine remobilization phase. The special attention is given to the problem of the world-uncommon Hg-tetrahedrite type of the ore deposits situated in the Mid-Bosnian Schist Mountains and their correlation with the almost identical tetrahedrite deposits in Tyrol (Austria) and Rudnany (Slovakia), both exclusively situated in the Palaeozoic strata. The solution of their genesis can help to the conception of the geotectonic evolution in the Dinarides.
