• Resumen

  • More than two hundred lutitic samples belonging to severa/ marine and non-marine evaporitic formations (Triassic to Upper Miocene) in the Iberian Peninsula were studied by the Rock Eval pyrolysis method and gas chromatography in order to document their potentia/ interest as source rocks for hydrocarbons. In general, all samples which are stratigraphically located close to or inter/ayered within sulfate or chloride (halite) layers show negative values. By contrast, sorne lutitic sequences displaying typical pre-evaporitic conditions in the marine Tertiary (Eocene, Messinian) basins give positive values
