On the other side of the terrane the Malvern Complex is composed of diorite and tonalite plutons that have been altered by Proterozoic metamorphism (modifying the original igneous textures) by still exhibit calc-alkaline, magmatic arc geochemical signatures. The date of emplacement is interpreted to be 677 Ma +/- 2 Ma with upper greenschist-lower amphibolite metamorphic cooling ages of c.650 Ma although crustal recycling is inferred from the presence of inherited zircon of 1598 Ma +/- 32 Ma. The later phases of intrusion are noted within the Wrekin Range where the Uriconian rhyolite is cross cut with the Neoproterozoic Ercall Granophyre.
