The Scremerston Formation is a geologic formation in England. It preserves fossils dating back to the Carboniferous period. [1]

Contents

It consists of layers of sandstone, siltstone, mudstone and coal, with occasional thin dolomite or limestone beds. Sandstones make up about 50% of the formation and are white, grey, brown or reddish brown, forming beds that are typically less than 15 m thick, but are known to reach 60m thick in places. The siltstones and mudstone layers are grey or brownish grey and non-calcareous. About 5% of the formation is made up of coal seams, which reach up to 1.5 m thick. [2] The Scremerston Formation was formed by the actions of a large river delta as well as marine deposits. [3] Evidence of the sedimentary layering is very evident along the cliffs at Cocklawburn beach near Scremerston, with plentiful marine fossils and pavement-like rock formations with wave-ripple cross-lamination.
