Balladoole (Carboniferous of the United Kingdom)

Where: Isle of Man, United Kingdom (54.1° N, 4.7° W: paleocoordinates 6.0° S, 0.2° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Gastrioceras hudsoni - Gastrioceras globostriatus ammonoid zone, Balladoole Formation (Great Scar Limestone Group), Asbian (340.0 - 336.0 Ma)

• Formerly called Poolvash Limestone or Poyllvaaish Limestones; Gastrioceras hudsoni & Gastrioceras globostriatus ammonite zones = B2a-b. Base of Gnatodus bilineatus conodont zone

• formation-level stratigraphic resolution

Environment/lithology: limestone

• Limestone, with interbedded subordinate claystone and siltstone at the top. Limestones vary from grainstone to packstone with bioherms of wackestone. Locally dolomitic. Limestones are typically grey and contain crinoids, brachiopods and corals. Large bioherms have been described up to 5m in height and 10m in width (Dickson et al.1987). Represents carbonate platform edge deposits. (From http://www.bgs.ac.uk/lexicon/lexicon.cfm?pub=BOOL)
