dc.description.abstractFrie emneord: Late Proterozoic Neoproterozoic Thirteen samples of Neoproterozoic rocks cropping out in the Vymskaya ridge have been collected for biostratigraphic work. The sampled sections, reaching a thickness of c.3000 m each, are exposed along the Dimtemyol and Pokju rivers. The succession consists of dark-grey, mainly muddy and shaly rocks, accumulated in a quiet basinal environment. The samples were processed and examinated at the Uppsala University in Sweden by Prof. Gonzalo Vidal. The samples contain only undeterminable organic detrius probably because the rocks have suffered too high thermal alteration for microfossils to be preserved. A poor assemblage of microfossils have previously been found in the same rocks. It was interpreted as suggestive of Terminal Riphean (kudashian) and Early Vendian age for the succession. A reexamination of this only existing collection, although poor, would possibly shed some supplementary light on its stratigraphic importance.
