Two sections, respectively in the Kruje-Dajt and Makareshi massifs of the Kruja Zone carbonate platform (located in the Apulian passive margin of Albania), and representing a period which extends from the Late Cretaceous to the Eocene, have been studied from several points of view : biostratigraphy, lithology and sequence stratigraphy. The proposed biozonation for the Late Cretaceous which has been established with benthic foraminifera (CsB4, CsB5, CsB6 and CsB7) improves substantially the stratigraphy for this period in this region. Eleven different facies (F1 to F11) characterise the Upper Cretaceous-Paleocene-Eocene carbonate sediments, and are distinguished for the first time. Fourteen sequences in the Kruje-Dajt massif and seven sequences in the Makareshi massif are recognized, using sedimentological criteria and clearly distinguished according to an established model for calcareous facies of this platform. Intense early dolomitization (sebkha type) is generally superimposed to the facies. The two sections represent a mostly homogeneous environment, evolving from the infra to supratidal environments. However, small variations of subenvironments are observed and linked to local and temporary variations of the platform. They are attributed to frequent eustatic fluctuations, and in two cases at least to instabilities of the platform which had cause emergencies and temporal discontinuities at the end of Cretaceous and early Eocene times (ca 20 and 5 m.y.).
