Struktura Pełczy – jeszcze jeden impakt z granicy K/T
The Povtcha structure – one more K-T boundary impact crater
Languages of publication
The shocked cherts and shattered marble breccia had been found in Povtcha, Volhynia, Ukraine in 2005 by Mariusz Paszkowski. The circular structure 10 km in diameter was identified using carthographic methods by authors. Probably, this is an impact crater. The age of the structure was determined to K-T boundary after analysing a sequence of Cretaceous and Tertiary beds.
