Palynodebris analysis of a shallow core from the Barents Sea
A quantitative study of palynomorphs and palynodebris in a shallow core from the central part of Bjbrn0yrenna. western Barents Sea, is presented. The core could be subdivided into a lower part characterized by a complete dominance of reworked plant debris of Mesozoic age and an upper part with consi...
