vicinity of Ferques, Bas-Boulonnais (Devonian of France)

Also known as Ferques Fm., Parisienne Mbr., vicinity of Ferques, Bas-Boulonnais

Where: France (50.8° N, 1.8° E: paleocoordinates 23.8° S, 4.1° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: upper Polygnathus asymmetricus conodont zone, Parisienne Member (Ferques Formation), Early/Lower Frasnian (383.7 - 382.4 Ma)

• upper asymmetricus conodont zone

• member-level stratigraphic resolution

Environment/lithology: marine; limestone

• "The Blacourt Formation is a compact, massive bedded, black fossiliferous marine limestone, with argillaceous layers and some small reefs in the Griset Member. The lower [Cambreseque] and upper [Patures] member of the Beaullieu Formation are mainly terrigenous ["shale" mentioned in figure caption], except for its lowest beds, the so-called Cedule Limestone. The middle [Noces] member consists of dolomite lenses, passing upward into shales, and to a reef build-up capped by fossiliferous limestones. The base of the lower [Fiennes] member of the succeeding Ferques Formation is a biostromal dolomite overlain by yellow, then brownis-dark dolomite and dolomitic sandstones. These are overlain by the fully marine fossiliferous Ferques Limestone. The lower part of the [second-from-bottom] Bois Member and the upper part of the [third-from-bottom] Parisienne Member are biostromal. In the upper [Gris] member, sediments are more argillaceous..."
