"Taken at the base of volcanic rocks overlying mudstones of Skiddaw Group; in parts defined by base of Overwater Formation. Angular unconformity seen in some localities (Millward and Molyneux, 1992); elsewhere proved from biostratigraphical evidence from underlying Skiddaw Group."@en . . . "High Ireby Formation [Obsolete: use EVG]"@en . . "Medium-K continental-margin type basalt-andesite-rhyolite volcanic association, transtional between tholeiitic and calc-alkaline affinities. Comprises porphyritic basalt, basaltic andesite, andesite and dacite lava flows and sills with intercalated volcaniclastic deposits, comprising tuff, lapilli-tuff, breccia, conglomerate and volcaniclastic sedimentary rocks."@en . "Andesite with subsidiary andesitic lapilli-tuff, andesitic tuff, basaltic-andesite, dacite, lapilli-tuff, pyroclastic-breccia, rhyolitic lapilli-tuff, volcaniclastic rocks (both pyroclastic and reworked volcanic rocks) and volcaniclastic-sandstone and trace volcaniclastic-conglomerate.
