Sažetak
Coarse-grained clastic sedimentary rocks, i.e. the collectors found in Miocene formation of the Ladislavci, Beničanci and Obod oil fields are sedimentary and genetically related to Miocene paleogeomorphology, synsedimentary tectonics and general transgression tendency during Miocene, particularly during the Badenian. The main types of the collector rocks and sedimentary bodies are as follows: 1. Clinoform bodies of carbonate rockfall and debrite breccias originated by accmulation of carbonate detritus along the slope and cliffs made of tectonized Mesozoic carbonate massifs on land, shore and partlly under sea level ; 2. Nearshore conglomerates originated by redeposition of carbonate rockfalls and debrites in nearshore marine shoals ; 3. Channel and fan bodies made of breccia-conglomerates and sandstones wich originated in submarine fans and/or deltas(?), and 4. Tectonic breccias, genetared by chrushing and tectonization of already lithified Micene turbidite sedimetary rocks, were accumulated in deeper environemts beloe the storm wave base simultaneously with kerogene pelitic (marlitic ) rocks (hydrocarbon souce rocks - oilshale).
