f Tectono-stratigraphic control of the generation, migration and trapping process in the irati-rio bonito petroleum system, santa catarina’s coalfields.

The work aims at the geological characterization of the structural and stratigraphic system responsible for the petroleum oils that occurs in Rio Bonito Formation, in the coalfields of Santa Catarina, Paraná Basin. Currently, it has been speculated that the geochemical signature of this oil is related to the Irati Formation associated with an unconventional model generation, by the thermal maturation of diabase intrusion, due to source rock insufficient burial. As the Irati is stratigraphically positioned above the Rio Bonito, the system is associated to a strong structural control for the migration model.
