Palynology of the interval 1856.4 to 1896.9 m of well 202/04-1, 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 202/04-1 was undertaken and samples were taken for palynology in order to provide additional facies information and age determinations. The palynological assemblages were generally dominated by terrestrially derived pollen and spores. Marine palynomorph assemblages, where present, were poorly preserved and of low diversity. Some samples showed no marine palynomorphs. A marginal marine setting with periodic more marine incursions is indicated. Four samples yielded sufficient dinoflagellate cyst data to suggest an Early to Mid Volgian age. This is supported by the presence of the spore genus Cicatricosisporites in most samples.
