Palynology of the interval 840.55 to 860.21 m of well 202/09-1, Faroe-Shetland Basin

As part of Phase 3 of the BGS Faroe-Shetland Consortium project on the Jurassic of the UK sector of the Faroe-Shetland Basin, detailed logging of core from well 202/09-1 was undertaken and samples were taken for palynology in order to provide additional facies information and age determinations. Analysis of the kerogen revealed assemblages dominated by black and brown woody and plant material Marine palynomorph assemblages were present only in the uppermost sample (840.55 m) where the dinoflagellate cysts Oligosphaeridium patulum and Perisseiasphaeridium pannosum indicate a Kimmeridgian to Early Volgian (Mutabilis to Pectinatus zones) age. The presence of the spore genus Cicatricosisporites in samples including sample 8 (856.54 m) near the base of the interval, indicates a Volgian or younger age and hence an Early Volgian age for the whole sample run.
