Current drilling activity focuses on the Marcellus, with more than 1,000 horizontal completions reported through mid-2015.

Geological Heritage B1 General geological description of the proposed Geopark The Black Country is situated in the centre of England adjacent to the city of Birmingham in the West Midlands (Figure. 1 page 2) .The current proposed geopark headquarters is Dudley Museum and Art Gallery which has the office of the geopark coordinator and hosts spectacular geological collections of local fossils. The geological galleries were opened by Charles Lapworth (founder of the Ordovician System) in 1912 and the museum carries out annual programmes of geological activities, exhibitions and events (see accompanying supporting information disc for additional detail). The museum now hosts a Black Country Geopark Project information point where the latest information about activities in the geopark area and information to support a visit to the geopark can be found.

Ludlow, Silurian) Positive Carbon Isotope Excursion in the Type Ludlow Area, Shropshire, England?
At what stratigraphical level is the mid Ludfordian (Ludlow, Silurian) positive carbon isotope excursion in the type Ludlow area, Shropshire, England? DAVID K. LOYDELL & JIØÍ FRÝDA The balance of evidence suggests that the mid Ludfordian positive carbon isotope excursion (CIE) commences in the Ludlow area, England in the uppermost Upper Whitcliffe Formation, with the excursion continuing into at least the Platyschisma Shale Member of the overlying Downton Castle Sandstone Formation. The Ludlow Bone Bed Member, at the base of the Downton Castle Sandstone Formation has previously been considered to be of Přídolí age. Conodont and 13 thelodont evidence, however, are consistent with the mid Ludfordian age proposed here. New δ Corg data are presented from Weir Quarry, W of Ludlow, showing a pronounced positive excursion commencing in the uppermost Upper Whitcliffe Formation, in strata with a palynologically very strong marine influence. Elsewhere in the world, the mid Ludfordian positive CIE is associated with major facies changes indicated shallowing; the lithofacies evidence from the Ludlow area is consistent with this. There appears not to be a major stratigraphical break at the base of the Ludlow Bone Bed Member. • Key words: Silurian, Ludlow, carbon isotopes, conodonts, chitinozoans, thelodonts, stratigraphy.
