Abstract: 

Ten key sections of the Iskâr Carbonate Group (Triassic) in Southwest Bulgaria have been studied in detail, and sampled for conodont and foraminiferal research. The biostratigraphic study covers the Ljubaš, Svidol, Mogila, Bosnek, Radomir, Rusinovdel, and Trân Formations that cover the chronostratigraphic range from the upper parts of the Spathian Stage to the upper parts of the Norian Stage. The conodont zones Paragondolella regale R.-Z., Paragondolella bulgarica R.-Z., Pridaella cornuta A.-Z., Pridaella exentrica A.-Z., Pridaella bakalovi R.-Z., and the foraminiferal zones Meandrospira pusilla I.-Z., Meandrospira deformata I.-Z., Pilammina densa R.-Z., Turriglomina mesotriasica I.-Z., Paraophthalmidium carpathicum R.-Z., and Miliolipora cuvillieri R.-Z., have been proven.

K. Будуров, Е. Трифонова, И. Загорчев. Трияс Юго-Западной Болгарий. Стратиграфическая корреляция ключевых разрезов Искырской карбонатной группы. Десять ключевых разрезов Искырской карбонатной группы (триас) было изучено в Юго-Западной Болгарии в детальях, и опробовано для исследования конодонтов и фораминифер. Биостратиграфическим исследованиям были подвержены Любашкая, Свидолская, Могилская, Боснекская, Радомирская, Русиновделская и Трынская свиты, которые соответствуют хроностратиграфическому интервалу от верхних частей спатского яруса до верхних частей норийского яруса. Были обнаружени конодонтные зоны Paragondolella regale R.-Z., Paragondolella bulgarica R.-Z., Pridaella cornuta A.-Z., Pridaella exentrica A.-Z., Pridaella bakalovi R.-Z., и фораминиферные зоны Meandrospira pusilla I.-Z., Meandrospira deformata I.-Z., Pilammina densa R.-Z., Turriglomina mesotriasica I.-Z., Paraophthalmidium carpathicum R.-Z., and Miliolipora cuvillieri R.-Z.
