The Pannonian Basin is the largest in the Intra – Carpathian region framed by the chain Alpine – Carpathian. It is a Neogene structure superimposed by compressional structures Mesozoic in the Alps, Denarii, and Internal Carpathians and above those, a tectonic type “strike-slip” Paleogene. During the Mio – Pliocene, the Intra – Carpathian area is characterized by a history of subsidence complex, controlled by orogenic evolution around. The temporal and spatial relations between the shortening of the folded belt and calkalkaline magmatism subsidence in the Intra–Carpathian area represent good indicators of the connection between those two dynamic phenomena (Săndulescu, 1998). This article will be analyzed the formation of hydrocarbon deposits in the Lower Pliocene Pannonian Basin regarding a case study. This structure will be analyzed in geological terms and also from the hydrocarbon prospects point of view.
