Abstract: 

The section of the Iskur Carbonate Group (Spathian-Norian) in the Vlahina Mountain is the southernmost occurrence of the peri-Tethyan (Balkanide type) Triassic in Southwest Bulgaria. Considerable lateral facies differences are recorded. A new Boychovtsi Member of the Lyubash Formation is introduced here for the first time. It is based upon the interbedding of limestones and marls with shales, and embraces the uppermost parts of the Spathian Stage and lower parts of the Anisian Stage. The Boychovtsi Member of the Lyubash Formation covers the thin variegated interbedding of the Svidol Formation, and is covered either by the Mogila Formation (section Boychovtsi) or directly by dolomites of the Bosnek Formation.

К. Будуров, Ив. Загорчев, Е. Трифонова, Л. Петрунова. Триас Юго-Западной Болгарии. Принос к стратиграфии Искырской карбонатной группы Влахина-планины. Разрез Искырской карбонатной группы (спатский-норский ярус) Влахина-планины является наиболее южным проявлением триаса перитетисского (балканидного) типа в Юго-Западной Болгарии. Установлены значительные латеральные фациальныс изменения. Выделен впервые новый член (Бойчовский член) Любашской свиты. Он основан на чередовании известняков и мергелей с аргиллитами, 11 отвечает самым верхним частьям спатского яруса и нижным частьям анизийского яруса. Бойчовский член Любашекой свиты перекрывает тонкую алтернацию Свидолской свиты, и перекрывается Оплетненским членом Могилской свиты или прямо доломитами Боснекской свиты.
