“…According to the adopted stratigraphical scheme of the Pădurea Craiului region (Cociuba, 2000), carbonate deposits of this age are known within the Vârciorog Formation, being previously attributed to the so-called "Upper Pachyodont Limestones" (fide Patrulius, in Ianovici et al, 1976). It is worth to mention that in the type-section of the Vârciorog Formations these limestones are not more than 15-20 m in thickness, while in the Subpiată section they are 120 m thick.…”

Establishing a clear stratigraphical succession of the Lower Cretaceous in Pădurea Craiului is not straightforward, as proven by the two main opinions expressed in the stratigraphical schemes elaborated by Dragastan et al (1989) and Dragastan & Ciobanu (2002) on the one hand, and by Bucur & Cociuba (1988), Cociuba (1999Cociuba ( , 2000, Bucur (2000) and Bucur & Cociuba (2001) on the other.

ABSTRACT. Two sections have been measured within the Lower Cretaceous deposits from the northern part of Pădurea Craiului: Osoiu Hill section and Subpiatră section. Thin sections representing more than 180 samples allowed us to present some results on the biostratigraphy, facies succession and the role of microbial structures in the genesis of these limestones. The Osoiu Hill section is dominated by fenestral limestones formed in the intertidal or in the shallow subtidal zone. Their formation is dominantly related to microbial mats. Based on foraminiferal assemblages we attribute a Lower Barremian age to these limestones. The succession in the Subpiatra section is dominated by shallow facies with rudists, corals and Bacinella. These limestones contain Mesorbitolina texana a foraminifer which indicate Gargasian age. A more dense spectrum of microbial structures characterize this section: thrombolitic crusts, Bacinella-Lithocodium type structures, cryptic carbonate marine veneers and rivulariacean-like cyanobacteria. The microbial structures played an important role in the genesis of carbonate sediments and their lithification in the two sections.

Abstract.Within the general succession of the Lower Cretaceous deposits from the Vârciorog-Dobreşti area (Pădurea Craiului Mountains), carbonate and terrigenous deposits were identified. The limestones were assigned to two distinctive lithostratigraphic units: the Valea Măgurii and Vârciorog formations. Based on the orbitolinids Palorbitolina lenticularis and Mesorbitolina texana their ages are assigned to the early Aptian, and respectively late Aptian-Albian. The terrigenous facies mainly include fine-grained deposits (clays, siltites, marls) and, to a lesser extent, coarser ones (glauconitic sandstones and conglomerates), and they are attributed to the Ecleja and Vârciorog formations. The marls of the Ecleja Formation have been observed in a single section. The lack of fossils prevents assigning an age to this marl succession. Based on their relative location, i.e., at the base of the late Bedoulian Valea Măgurii Limestones, they may be assigned to the early Aptian (early Bedoulian). The siliciclastic deposits of Vârciorog Formation cover the largest areas in the region. Their late Aptian-Albian age is established based on the presence of Mesorbitolina texana. Additional arguments are represented by an ammonite fauna assigned to the terminal Bedoulian-early Gargasian. This fauna is located at the base of the Vârciorog Formation. The Lower Cretaceous deposits cropping out in this area have been investigated in seven geological sections. The data interpretation allowed a synthetic reconstruction of the succession and of the depositional environments.
