Tectono–Stratigraphic Position of the Kaminnyi Potik Unit in the Ukrainian Carpathians and Volcanogenic Rocks of Mt Chyvchyn

Geology of the volcano-sedimentary complex of the Kaminnyi Potik Unit on Chyvchyn Mountain (Ukrainian Carpathians): preliminary results

“…(Hnylko et al, 2007) and is de vel oped as thin-bed ded light and dark grey micritic lime stones with lenses of dark cherts, and is interbedded with coarse/fine-grained cal car e ous pyroclastic turbidites (flysch) 6 and 7C,D ). It is sim i lar to the stratotype of this for ma tion in the Kamyanyi Potik Stream, near Rakhiv (Krobicki, 2012;Krobicki et al, 2014). Near the trail that goes around the north side of the Chyvchyn Mt., there are out crops of pyroclastic flysch -turbidites with graded tex tures that con tain sig nif i cant amounts of vol ca nic ma te rial.…”

“…The Kamyanyi Potik Unit (Nappe) is the struc tur ally-high est and most in ter nal unit of the Fore-Marmarosh Nappes (flysch prism), and in many places is di rectly cov ered by the Marmarosh base ment nappes. But its con nec tion with the sur round ing units is still a mat ter of dis cus sion (Boyko, 1970;Vialov et al, 1981;Kruglov, 1986;OEl¹czka et al, 2006;Krobicki et al, 2014). Boyko (1970) in ter preted this unit as be ing part of the Radomyr Zone of the Marmarosh Mas sif, Vialov et al (1981) re lated it to the Rakhiv Nappe (Unit), and Kruglov (1986) and OEl¹czka et al (2006) con sid ered this unit to be a part of the Marmarosh Nappes.…”

Discussion of ‘Olistostromes of the Pieniny Klippen Belt, Northern Carpathians’

“…The origin of the mid-oceanic Czorsztyn Ridge was connected with the Bajocian syn-rift geotectonic reorganization (Krobicki & Wierzbowski, 2004, 2009, 2014; Krobicki, 2009) and is coeval with the spreading phase of the Alpine Tethys (see also Lewandowski et al 2005). The occurrence of the mafic (basalt) intrusions in the eastern termination of the Czorsztyn Ridge seems to support the thermal origin of the ridge related to the oceanic spreading (Golonka et al 2005 b ; Krobicki et al 2005, 2006, 2008, 2014 a , b ; Oszczypko et al 2015; Hnylko et al 2015). The palaeogeographic position of the Alpine Tethys was depicted in our paper (Golonka et al 2015, in fig.…”
