The presence and abundance of n-alkane, n-metil ketones, n-etil-ketonés, n-butil ketones and elemental sulphur are compared. Samples from Ebro basin bore hole core (PE-1) reveal alternances of "terrestrial" and "acuatic" lacustrine environmental conditions (shallowing versus deepening conditions) while samples from Duero basin borehole core (VS-1) show a constant "terrestrial (shallow) characterspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/BiomarquersN-alkaneKetonesElemental sulphurLacustrineCainozoicDuero BasinEbro Basinjournal articleopen access
