The Malvern Hills represent another depositional environment for Late Neoproterozoic sedimentation with the Warren House Formation being in thrust contact with the Malvern Complex. The Warren House Formation is composed of pillow basalts, intermediate lavas, altered rhyolites and welded and non-welded acid tuffs with evidence to suggest that they are linked via fractional crystallisation. U-Pb zircon dating gives an age of 566 Ma+/-2 Ma. The geochemical signature from this sequence is contrasting to that of the rest of the Wrekin Terrane being of a volcanic arc formed on oceanic or on thin, immature continental crust.
