Abstract

The deposits of the Niżniów Formation, exposed around Niżniów, mainly on the banks of Dnister River, accumulated in the most proximal, marginal position of the latest Jurassic-earliest Cretaceous epicontinental basin on the SW margin of the East European Platform. The Niżniów Formation directly onlaps a Palaeozoic substrate and consists of transgressive cliff-derived conglomerates, and sandstones and marls which pass laterally into shallow marine carbonates: mainly biomicrites, oncomicrites, and pelmicrites with an abundant benthic fauna dominated by nerineid gastropods. The thickness of the formation in the area studied ranges from 0 to more than 20 metres and was controlled by morphology of the pre-transgression substrate (mainly built of Devonian clastic rocks), synsedimentary fault tectonics and pre-mid-Albian erosion. The age of the Niżniów Formation can be determined, on the evidence of benthic foraminifers encountered in thin sections, as most probably late Tithonian-early Berriasian.
