- •
An expanded high resolution δ13Corg curve was obtained for the Organyà Basin.
- •
The results provided no evidence of full anoxia within the studied section.
- •
Episodic dysoxic conditions enhanced OM preservation during the lower-middle Aptian.
- •
High sedimentation rates induced preservation of OM from different sources.
- •
Tectonic and eustatic changes generated abrupt facies modifications at El Pui.
