Nevertheless, his work waited for more than fifty years for confirmation. It could be said that Milankovic?s work had most influence in creation of Astronomic Time Scale, supporting of continental drift hypothesis and palaeoclimatology implications. Positive results of the implementation of the astronomic time scale to the Neogene stratigraphy initiated the application of this method within the Mesozoic, and lately also to the Paleozoic sediments. Milankovic?s manuscript of astronomical forcing of climate changes led to fruitful cooperation with Alfred Wegener who was searching for additional arguments to validate his continental drift hypothesis. The factors that cause climate changes enable insight to the geological past, but also the possibility to model the climate conditions which await us in the future. Climate change prediction allowed people, as only being aware of its influence, to act preventively and take all measurements needed to reduce greenhouse gasses emission.","PeriodicalId":378337,"journal":{"name":"Annales g?ologiques de la Peninsule balkanique","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127359970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inside this part of the succession open-marine influenced layers are rare. The succession continues with a partly turbiditic sequence and chaotic rudstones, densely packed with reef-derived material like broken reefbuilding organisms and shallow-water material like gastropods, bivalves and foraminifers.

The prominent position among a number of Middle Miocene (Badenian) fossiliferous sites in the vicinity of Belgrade (southern Pannonian Basin, Central Paratethys) are occupied with sediments of Rakovica stream, also known as ?Rakovica sands?. Here, the integrated evidence based on new fossil findings of calcareous nannoplankton, foraminifera and molluscs assemblages, allows the stratigraphic revision of the clastic facies of the Rakovica succession. Based on the studies of lithological composition, high paleodiversity molluscs fauna and local palaeogeographical setting, it can be concluded with reasonable certainty that deposits of Rakovica stream entitled ?Rakovica sand? represents a sandstone of the shallow marine (littoral) environment during Lower Badenian time.

This is supported at its southern margin by the presence of thermophilous mollusc taxa, as well as the Conidae, Strombidae, Xenophoridae, Pleurotomidae, Turridae, Muricidae, etc. Consequently, the investigated deposit can be ascribed to the early Badenian which biostratigraphically corresponds to the nn5 nannozone by correlation with successions in theirs type-areas to the Central Paratethys, and defines preciously the time of the marine transgression in this area.","PeriodicalId":378337,"journal":{"name":"Annales g?ologiques de la Peninsule balkanique","volume":"341 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115270026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
