Sažetak
Statistical analyses were applied to the Late Cretaceous clastic deposits exposed along the flanks of the Mali Potok creek in Medvednica Mt., as an auxiliary tool in order to help determining the source of pebbles, depositional processes and position within the sedimentary basin. Particularly interesting is the comparison of the conglomerate matrix with the overlying sandstone. Matrix grain size exhibits normal distribution, with most abundant fractions between 0.125 and 0.5 mm and sorting coefficient 2.14. Sandstones are grain- supported, well sorted, with coefficient value 1.55. Asymmetrical distribution, with domination of small-sized clasts between 0.032 and 0.125 mm in diameter characterizes these deposits. Such distribution is in concordance with interpretation of sandstones as synorogenic turbidites. Clastic succession from Mali Potok Creek can be well compared with contemporaneous deposits in the wider area, particularly with recently studied clastic succession in the vicinity of the Medvedgrad Castle.
