Abstract

In the article, based on own field observations, the deformation structures into the thrust zone of the Zelemianka Skyba (=thrust-sheet) onto the Parashka Skyba (the Ukrainian Carpathian Skyba Nappe) are described. They are exposed in the Hrebeniv quarry located in the Opir River basin (Lviv Region, Skole district). The tectonically disintegrated Stryi Formation (Upper-Cretaceous–Paleocene flysch) characterized by the rigid sandstone blocks (formed mainly as a result of boudinage) placed in a ductile clay matrix is represented in the Hrebeniv quarry. This formation is proposed to be classified as a “broken formation”, which is strongly tectonized, but retain their lithological and stratigraphic identity. It is a transitional element between the weakly deformed strata and tectonic mélange. Their characteristic features are: linearity of the distribution zone; significant monomictic composition and absence of exotic formations; the presence of an intensively tectonized matrix with clastolites (blocks) of less tectonized rocks of the same lithostratum (formation, series); the presence of newly formed hydrothermal minerals in clastolite cracks; the upper and lower contacts limiting the broken formation have a tectonic nature. An intensely tectonized matrix and a weakly tectonized rigid blocks belong to the same stratigraphic unit in a broken formation. The structural features suggest a brittle deformations in the studied rocks. Tectonic processes occurred in the completely lithified deposits. Thrust processes were accompanied by the formation of the duplexes, including antiformal stack duplexes, which are well expressed in the quarry. Duplexes are observed in different parts of the quarry, and the most representative ones are developed in its central section. Horses in the duplexes are characterized by a size of 1 to 3 meters here. They are generally subparallel, which is consistent with monoclinal bedding, however, they sometimes acquire an antiform appearance as a result of tectonic thrusting.

Abstract

The results of micropaleontological and sedimentological studies of the Paleocene sediments such as the Upper Member of the Stryi Formation and the Yamna Formation located in the Skyba Nappe in the Ukrainian Outer (Flysh) Carpathians are represented. Sedimentological features of the flysch successions (including the sedimentary succession along the Prut River in the city of Yaremche) proved that the Upper Member of the Stryi Formation is represented mainly by turbidites; the lower part of the Yamna Formation (variegated Yaremcha Horizon) is composed of red and green clay hemipelagites and turbidites, and the upper part of the Yamna Formation (Yamna sandstone) consists of deposits of high-density turbidite currents and grain flows.

The calcareous nannoplankton: NP1, NP2, NP3 and NP4 zones as well as the foraminifera: planktonic Globoconusa daubjergensis Zone (Danian Stage) and benthic Rzehakina epigona Subzone of Rzehakina fissistomata Zone, s. l. (the early Paleocene) are identified in the Upper Member of the Stryi Formation. The calcareous nannoplanktonic NP4, NP5, NP6 zones are distinguished in the Yaremcha Horizon and NP6, NP8, NP9 zones are identified in the Yamna sandstone. The agglutinated foraminifera including Rzehakina fissistomatа, Rz. epigona, Caudammina ovula, Hormosina velascoense, Glomospirella grzybowskii, Saccammina placenta, Paratrochamminoides irregularis are dominated in the Yamna Formation. The age of the Stryi Formation (Upper Member) is established as Danian–partly Zealandian, and the age of the Yamna Formation is Zealandian–Thanetian based on nannoplankton and foraminifera data.

Deep-water agglutinated foraminifera (DWAF) belonging to the genera Rhabdammina, Hyperammina, Dendrophrya, Ammodiscus, Glomospira, Hormosina, Reophax, Haplophragmoides, Recurvoides, Trochamminoides, Paratrochamminoides, Spiroplectammina, Karreriella are dominated in the background hemipelagic clay deposits and make up to 100% of the tests in the microfaunal associations, that suggests the lower bathyal-abyssal depths of the sedimentary paleobasin The channel deposits (Yamna sandstone) and interchannel sediments (Upper Member of the Stryi Formation) of the ancient deep-sea fan are identified in the Paleogene flysch.
