Pettycur, Bottle Factory, Bottle Factory Sediments (Carboniferous of the United Kingdom)

Where: Scotland, United Kingdom (56.1° N, 3.2° W: paleocoordinates 3.9° S, 0.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pettycur Volcanics Formation (Upper Oil Shale Group), Asbian (339.4 - 336.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; dolomitic shale and graded tuff

• The Bottle Factory section is composed of two [lava] flows, the upper flow being columnar in part with the joints filled with tuff cemented in carbonate. The lavas are underlain and overlain by locally developed impersistent dolomitic mudstones. Of these, the mudstone above the second flow is the most persistent and appears to be developed within depressions in the old lava surface. In places this lithology yielded plant compression fossils, mainly of lycopods and pteridosperm leaves. Above this sequence a thick series of shales, silts and graded tuffs is exposed.This lava and interbedded sediment sequence thins southwards and disappears on the beach section at Pettycur Harbour.
