A. NEOGENE EVOLUTION OF THE EASTERN CARPATHIAN FORELAND BASIN
(EASTERN POLAND AND UKRAINE)


The Carpathian Foredeep Basin is the northern compartment of a foreland basin system that surrounds the Carpathian Orogenic Belt. During the field trip the sedimentary characteristic of the Miocene deposits on the area belonged both to the northern part of the outer ramp of the Carpatian Foredeep Basin and to the Paratethys Basin will be presented, in the territories of Poland and Ukraine.

The characteristic of the Miocene succession allows an interpretation of the environment and its change during sedimentation, from the high-energy, shallow-water, normal-marine environment, through the saline conditions, up to the coralline algal and serpulid-microbialite build-ups.

Diversified sets of sedimentological structures, including depositional, deformational and biogenic will be presented during the field trip:

Łysaków Quarry
Badenian, Sarmatian, serpulid-microbialite reefs, Poland

Pardysówka Quarry
Badenian, calcarenites, different scale sets of depositional structures, channel-like forms, Poland

B. CATASTROPHIC SEDIMENTARY PROCESSES ON THE SILURIAN CARBONATE PLATFORM OF PODOLIA, UKRAINE

Dozens of excellent, easily accessible natural exposures on high banks of Dnister river and its northern tributaries, numerous quarries, almost horizontal strata, and abundance of fossils - all these put the Silurian sections of Podolia (western Ukraine) among the most interesting in the world.

In the Middle and Upper Silurian the Podolia region formed part of a carbonate facies belt that rimmed the East European Craton. The central position in the belt was occupied by stromatoporoid-coral shoals and barriers, which separated inner shelf facies, represented mainly by laminites and dolomicrites with eurypterids and ostracods, from outer shelf deposits, dominated by limestones and marls with abundant and diversified benthic fauna. The main factor that caused shifting of sedimentary environments in consecutive time intervals were the eustatic fluctuations of the sea level. The sedimentary record of these changes is, however, largely obscured by catastrophic processes, such as extremely fierce hurricanes or tsunami wave surges that caused local erosion and mass onshore redeposition of material, mainly of massive stromatoporoids. Their most common effect is the appearance of thick, stromatoporoid rich beds within fine-grained peritidal deposits.

Several examples of various effects of catastrophic sedimentary processes in shallow water carbonate facies will be presented during this part of field trip:

Kubachivka Quarry
Ludlow, stromatoporoid-coral barrier facies, intertidal facies, onshore redeposition of outer shelf material

Skala Podil'ska - Zbruch river escarpment
Pridoli, peritidal succession, incised tidal channel filled by stromatoporoids

Skala Podil'ska Quarry (?)
Pridoli, lagoonal facies, subaerial exposure, initial regoliths, washover flats

In the same region is also possible to visit magnificent exposures of the Podolian Old Red facies near Zaleschtchyki. The sightseeing of Lvov and Kamjanec Podilskij are also included into the programme of this 5-day trip.
