Fifty-two samples of Miocene pelitic sedimentary rock from outcrops on Medvednica,Moslavacka Gora and Psunj Mts.,and boreholes in the Sava Depression and the Pozega Sub-depression were *** sediments formed in different marine（with normal and reduced salinity）,brackish,and freshwater environments,depending on the development stage of the Pannonian Basin *** minerals,clay minerals and quartz are the main constituents of all pelitic sedimentary rocks,except in those from Moslavacka Gora Mt in which carbonate minerals are not ***,pyrite,opal-CT,and hematite are present as minor constituents in some *** calcite,dependent on the sedimentary environment and diagenetic changes,high-magnesium calcite,aragonite,dolomite and ankerite/Cadolomite are also *** or illite-smectite is the main clay minerals in the *** constituents,present in almost all samples,are detrital illite and *** some samples chlorite is also present in a low *** elements,trace elements and rare earth elements patterns used in provenance analysis show that all analysed samples have a composition similar to the values of the upper continental crust（UCC）.The contents of major and trace elements as well as SiO2/Al2O3,K2O/Al2O3,Na2O/K2O,Eu/Eu＊,La/Sc,Th/Sc,La/Co Th/Co,Th/Cr,Ce/Ce＊ and LREE/HREE ratios,show that the analysed pelitic sedimentary rocks were formed by weathering of different types of mostly acidic（silicic）,*** rocks.
