The palynology of Faroe-Shetland Basin well 204/19-1 (4209.4 to 4222.8 m)

During Phase 3 of the BGS Faroe-Shetland Consortium project on the Jurassic of the UK sector of the
Faroe-Shetland Basin, graphic/lithological logging of core from well 204/19-1 was undertaken. Five
samples for palynology between 4209.40 and 4222.80 m were collected in order to provide age
determinations and palaeoecological interpretations.
The palynomorph assemblages were extremely sparse with the exception of sample 5 at 4222.8 m. This
horizon yielded an Early Cretaceous dinoflagellate cyst flora indicative of a maximum age of earliest
Barremian. Other elements in sample 5 suggest that a post Barremian age is unlikely but not impossible.
The remainder of the samples, between 4209.4 and 4219.55 m produced sparser palynobiotas which are
devoid of marker species. Marine deposition prevailed throughout the succession investigated.
