Abstract

A complicating factor in correlating Cambrian sections in Britain and Ireland is that host terranes now geographically close to one another may have been widely separated in Cambrian time. This section reviews a terrane map of Britain and Ireland (Fig. 5) and its implications for Cambrian cor- relation. There are intrinsic limitations in palaeomagnetic res- toration of terranes to their geographic positions in Cambrian times. Additional evidence is available from faunal distri- butions, tectonic reconstructions, and isotopic characterization of sediment source areas. Using these methods, some con- straints can be put on the Cambrian positions of terranes relative to each other and to the major continents from which they were detached in post-Cambrian time. Some Neoprotero- zoic relationships are also discussed, because of doubts in some terranes as to whether late Neoproterozoic successions range up into the Cambrian.
