The Middle Triassic, Muschelkalk carbonates of southern Poland, encompass open marine sediments formed at the northern boundary of the Western Tethys Ocean. Therefore these deposits differ significantly from those deposited in the inner, more restricted part of the Germanic basin. The Muschelkalk in southern Poland abounds in tethyan faunal elements, including one of the oldest scleractian assemblages. The corals together with sponges built spectacular bioherms and reefs, perfectly outcropped in Upper Silesia. As a whole the faunal composition indicates close liaisons of the Middle Triassic from southern Poland with its equivalent in Southern Alpes.
Numerous quarries enable detailed field observations of sedimentary fabrics, facies arrangement and geometry of the sedimentary sequences. Moreover, owing to paleotectonic position within the reactivated Variscan faults, the carbonates of Silesia display many sedimentary and deformational structures diagnostic of syndepositional crustal mobility and seismicity.
The excursion will be focused on sedimentary processes typical for transitional zone between open ocean and its periphery, 3rd order sedimentary sequences and high-frequency sedimentary cyclicity analysed in terms of eustasy vs. synsedimentary tectonics.
Field trip details:
The excursion will depart from the Institute of Geological Science, Jagiellonian University, Oleandry Str 2a, Kraków (just close to our conference centre) at 8 a.m. on June 26. It will be back in Kraków the next day approximately at 7 p.m. There will be a possibility to deposit the luggage in safety room in the Institute of Geological Science for excursion days
First day - Kraków - Libiąż - Jaroszowiec - Żyglin - Zawadzkie - Kamień Śląski
Second day - Kamień Śląski - Tarnów Opolski - Strzelce Opolskie - Kraków
The distance to cover is approximately 250 km first day and 200 km second day. Several active quarries will be visited. Participants are asked to bring basic field equipment. The helmets and safety jackets indispensable in the active quarries will be provided by the organizers.
