欧洲一侧的每个造山期能与北美一侧的一个造山期相关联吗?也就是说,同一个造山运动有两个名字?
在更细的尺度上是否可能存在相关性? For example the Caledonides in Scotland are marked by some very prominent ancient faults (Great Glen, Moine, and Highland Boundary Faults). The Appalachians also have some large fault systems. Can any of these be correlated across the Atlantic? Can specific sedimentary sequences be correlated? (I realise that big picture sequences in the late Palaeozoic are broadly similar, e.g. Permian Aeolian Sandstones, Carboniferous Deltaics & Coal, etc)
