|Derivatio nominis||Named after the east Scottish town and seaport of Tayport. The formation was defined by Cameron (1993a)|
|Type section||Location map||See figure (pdf)|
|Depth||2755 to 3200 m|
|Length||445 m along hole|
|Definition||Red to red-brown and grey claystones and siltstones, interspersed with well-developed sandstone beds. The upper part of the formation is predominantly grey.|
|Upper Boundary||The contact with the conformably overlying Cementstone Formation is characterized by the first occurrence of limestone beds|
|Lower Boundary||The formation overlies the distinctly more sandy Buchan Formation, probably conformably|
|Distribution||The limited amount of data available indicate the presence of this formation in the Dutch offshore area on the Elbow Spit High area and part of the Mid North Sea High. In the UK, it is known to occur in the Central Graben, the Western Platform and the Outer Moray Firth Cameron (1993a) .|
|Age||The upper part of the formation in the Netherlands continental shelf yielded palynomorphs indicating a Tournaisian (Courceyan) age. Diagnostic biomarkers include Spelaeotriletes lepidophytus and Raistrickia varia-bilis. In the United Kingdom the age extends into late Dinantian.|
|Depositional Setting||The formation was deposited in a fluvial setting. The sandstones are fluvial channel fills, partly stacked to form thicker sandstone units. The clay- and siltstones were deposited on a floodplain, at times well-drained, which caused a red colouration.|
