The borehole 6042 Deleni is among the few wells located in the central part of the Transylvanian Depression that crossed the rocks in the basement. Among these, the Mesozoic deposits were cross-cut along 916 m. Based on the investigations carried out on core samples from the Mesozoic deposits three carbonate units attributed to the Late Oxfordian -Tithonian (?Neocomian) have been separated. A preliminary evaluation of the terrigenous and carbonate-terrigenous deposits overlaying the carbonate ones indicated an Aptian-Albian, respectively Senonian age. Considerations on the paleoenvironment of the Mesozoic deposits studied are also presented.
