The Pre-Cambrian Era, to correlate them. A few interesting fossils have been found in the younger Pre-Cambrian rocks, but it remains generally true to say that there are none of stratigraphical value. Isotopic dating is therefore of great value and most correlation of Pre-Cambrian rocks is based upon it, especially as t

The Lower Palaeozoic Geosyncline,folding movements, into a folded-mountain chain. A geosyncline (Fig. 5) can be defined as an elongated downwarping of the crust of the earth, forming a deep trough in which a great thickness of sediments accumulates. This definition needs to be somewhat enlarged. First the downwarp is occupied by th

The Caledonian Mountain-building,he Lower Palaeozoic era (Fig. 7), these movements being named the Caledonian Orogenesis; one can hence speak of Caledonian structures having been imposed on the rocks and of the Caledonian mountains having been produced. As mentioned above, there were several periods of folding of the geosyncline du

The Upper Carboniferous Deltas and Coal Swamps,and with lavas, described above, continued uninterruptedly into the Upper Carboniferous. Further south, as now seen in the southern Pennines, North and South Wales, conditions changed at this time and another series of great deltas began to be built outwards from the neighbouring land areas. These d
