Sažetak
The diamicts are interpreted herein as tills that were deposited in the base of a temperate glacier, but more research is due to decipher the course of the ice movement. The till distribution documents that the whole of the Medvednica Mt. was covered by active glacier(s), which was first speculated by Pilar in 1877. The presence of encrusted lithoclasts and Miocene skeletal debris in the Gornje Orešje diamict is a major problem to be solved in the future, but it might have been reworked by glacier ploughung from nearby sources. These new data, along with previously reported data on the glaciation of the Medvednica Mt. (Marjanac et al. 2013) and Krško environs in Slovenia (Poljak et al. 2013a, b) document very wide extent of Pleistocene glaciation in north-western Internal Dinarides, and call for the reinterpretation of sediments which were identified on previous maps as Plio-Quaternary "basal conglomerates" (Šikić et al. 1978, Basch 1983, Šimunić et al. 1983). The age of Medvednica glaciation is yet unresolved because of the lack of datable matherial, but the dating of diamicts from the Krško environs in Slovenia (Poljak et al. 2013 a, b) provide Middle Pleistocene age.
