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.
