ABSTRACT
Several organic-rich samples taken from upper Santonian–late Campanian(?) laminated limestones of Hvar Island (Croatia) were investigated to characterize palynofacies, macerals, type of organic matter, and organic geochemistry. These characterizations, as well as the reconstruction of the depositional environment, are interpreted in terms of a source rock perspective.
The results suggest that the laminated limestones were formed within shallow depressions of the carbonate platform in an anoxic, restricted-marine environment with increased salinity.
The Hvar Island laminated limestones contain type II-S kerogen, and they are found to be marginally mature and oil prone.
