(Carpatho-Balkanides, eastern Serbia) are presented. On two localities, near the village Faca Vajali, four types of microfacies and one subtype within the bioclastic limestones were separated. The characteristics of the depositional environments of the investigated Urgonian Limestones were studied and are discussed. At the base of the established rich microassociations of foraminifera and algae, the vertical distribution of foraminiferal species was precisely defined which enabled the determination the the age of this part of the Urgonian Limestones as Late Barremian-Early Aptian. %K Late Barremian-Early Aptian %K Urgonian Limestones %K Sedimentology %K Micropaleontology %K Stratigraphy %K Ku aj Mountains %K eastern Serbia %U http://www.doiserbia.nb.rs/img/doi/0350-0608/2008/0350-06080869013S.pdf
