- Аннотация: Abstract—A thick olistostrome strata of late Paleocene–early Eocene age is outlined in the northern flank ofthe Northwestern Caucasus folded structure in the Ubinka river valley, which shows the significant role of earlier Cenozoic tectonic movements in forming the alpine structure of the region. The largest part of the stratais composed of dark weakly calcareous clays, which were earlier recognized as Lower Cretaceous deposits.Olistoliths and large olistoplaques are mostly of light calcareous rocks in which microfauna of Cenomanian and Maastrichtian ages were discovered in dark clays. A poor series of foraminifers was recognized in the dark clays hosting these olistoliths; this series do not enable one to determine with certainty the age of the strata(of approximately the late Paleocene–early Eocene). Small structural forms were recognized in olistoliths and olistoplaques, which are not traced in the matrix, this indicates that a series of folded and fissured struc tures were formed before these olistoliths and olistoplaques appeared in the olistostrome strata. Keywords: Olistolith, olistostrome, Paleocene, Eocene, NorthWestern Caucasus, folding.
