Three potential hidrocarbon reservoirs are defined for this domain, the Hettangian Basal Dolomitic-Evaporitic Unit, the Lower Sinemurian Shallow Carbonate Ramp and the Middle Dogger Neritic and Pelagic Ramps, that mightget hidrocarbons from middle liassic organic-rich marls and black shales source-rocks developed in the adjacent Polientes-Sedano Basin PB Sociedad Geológica de España YR 1992 FD 1992 LK http://hdl.handle.net/10272/14120 UL http://hdl.handle.net/10272/14120 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
