Alabaster from the Carpathian Foredeep in the architecture of Cracow

Alabaster is a rock with low hardness, high coherence, fine-crystalline development and forms an optically “warm” surface when polished. It has been used as a sculpting, decorative and architectonic stone, often by civilizations of the Mediterranean Sea Basin. Alabaster in the architecture and sculpture of Kraków is mainly from the Middle Miocene (Badenian) and comes from deposits within the Ukrainian Carpathian Foredeep Basin, chiefly along its northern margin in the “Podolia rim”. It was quarried around the mid-part of the Dnister River and its tributaries, from Lviv (Lwów) to Khotyn (Chocim), and mostly at Zhuravno (Żurawno). The alabaster quarried here was called Ruthenian, Polish, or Lvov “marble”. Small quarries were also located at the front of the Carpathian overthrust, including the known deposit at Łopuszka Wielka. The Miocene alabaster has shades of white, yellow, green, brown, usually with differing spots or veins; often the rock is brecciated and partly semi-transparent. Alabaster has been quarried in the Polish Republic since the 16th century, peaking (also in finished stone products) between the world wars. The authors present examples of alabaster usage in ecclesiastical edifices of Kraków, for instance in the Wawel Cathedral, St. Mary’s Church, the churches of Dominican, Carmelite and Missionary clergy, and also in some secular buildings, e.g. the Jagiellonian Library.

Radiolarian and agglutinated foraminiferal biostratigraphy of the Paleogene deep-water deposits on the northern margin of the Carpathian Tethys (Skole Unit)

Radiolarian and agglutinated foraminiferal fauna within upper deposits of the Skole Unit of the Polish Flysch Outer Carpathians occur in the Variegated Shale and Hieroglyphic formations of Paleocene and Eocene age. About 70 radiolarian and 50 foraminiferal species have been identified and their stratigraphic distribution determined using both regional and local biozonations. Five radiolarian zones: the Bekoma bidartensis Interval Zone, the Buryella clinata Interval Zone, the Phormocyrtis striata striata Interval Zone, the Theocotyle cryptocephala Interval Zone and the Dictyoprora mongolfieri Interval Zone in the lower Eocene and in the lower part of the middle Eocene have been distinguished. In the upper part of the middle Eocene and in the uper Eocene the abundance of radiolarians decreases and their age assignment has not been possible. Five foraminiferal zones have been distinguished and correlated with radiolarian zones based on co-occurrence of both Protista groups in the deposits investigated. These are: the Rzehakina fissistomata Zone, the Saccamminoides carpathicus Zone, the Reticulophragmium amplectens Zone, the Ammodiscus latus Zone and the Cyclammina rotundidorsata Zone covering the time span from upper Paleocene to upper Eocene.
