Short Paper: Movement on proposed terrane boundaries in northern Britain: constraints from Ordovician–Devonian igneous rocks

M. F. THIRLWALL

Department of Geology, Royal Holloway and Bedford New College, Egham, Surrey TW20 0EX, UK

Regional chemical and isotopic differences seen in Ordovician–Devonian igneous rocks of northern Britain are thought to be due to subduction-related and collision magmatism tapping a variety of mantle and crustal sources. Matching of spatial chemical variation across major fault zones restricts post-magmatic transcurrent movement north of the Southern Upland Fault (SUF) to a few tens of kilometres on each fault. A unique mantle isotopic signature present in the same area may restrict post-1.5 Ga movement to less than a few hundred kilometres. No such restrictions exist on displacement across the SUF, to the south of which all magmas show a Pb isotopic component derived from southern sources.
