Sedimentology and hydrocarbon habitat of the submarine-fan deposits of the Central Carpathian Paleogene Basin (NE Slovakia)

Abstract The Central Carpathian Paleogene Basin accommodates a subsiding area of the destructive plate-margin. The basin history comprises marginal faulting and alluvial fan accumulation (E 2 ); transgressive onlap by shoreface sediments and carbonate platform deposits (E 2 ); glacio-eustatic regression induced by cooling (Terminal Eocene Event); forced regression, tectonic subsidence and growth-fault accumulation of basin-floor and slope fans (E 3 ); decelerating subsidence, aggradation and sea-level rising during the mud-rich deposition (O 1 ); high-magnitude drop in sea-level (Mid-Oligocene Event), retroarc backstep of depocenters and lowstand accumulation of sand-rich fans and suprafans (O 2 –M 1 ); subduction-related shortening and basin inversion along the northern margins affected by backthrusting and transpressional deformation (O 2 –M 1 ). The basin-fill sequence has poor (TOC≤0.5%) to fair (TOC
