Palynology of Faroe-Shetland Basin well 205/26a-4 between 2454.39 and 2498.91 m

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 205/26a-4 was undertaken. Twenty core samples were taken for palynology between 2454.39 and 2498.91 m in order to provide age determinations and additional facies information. The uppermost succession (2454.39 to 2469.17 m; samples 1 to 11) is considered to be of Late Jurassic to earliest Cretaceous (Mid Volgian to Early Ryazanian) age based on sparse dinoflagellate cysts, which include the marker species Perisseiasphaeridium insolitum. The interval between 2470.67 and 2498.91 m (samples 12 to 20) proved palynologically barren, therefore no age assessments are possible.
