The Edale Shales are early Namurian in age. Mam Tor outcrop allowed examination of the Edale Shale and the Mam Tor Beds. The trip allowed examination of the source rocks for the fluids, reservoir and host rocks within the Lower Carboniferous limestones also examples of hydrocarbon and MVT mineralisation. We discussed the source and migration of the metalliferous fluids responsible for the emplacement of Pb, Zn, F, Ba Mississippi Valley-type (MVT) mineralisation on the Derbyshire Platform. The excursion provided an opportunity to examine all elements of the hydrocarbon system. The late Visean to Namurian succession of carbonates and clastics, together with the regional setting, offered an excellent opportunity to examine an exhumed hydrocarbon system, which is analogous to the East Midlands hydrocarbon province in Nottinghamshire and Lincolnshire. On a hot and sunny day a group of ten MGA members and guests visited key outcrops near Castleton. The full, illustrated newsletter is available as a pdf for download.
