Lapworth (1879) founded the Ordovician System on the basis of British successions, the correlation of which has continued to be of importance in the global understanding of some 45 Ma of Earth history. The Geological Society Special Report on the correlation of the Ordovician (Williams et al. 1972) was the third in the series of Special Reports, and is now out of print. This provided the first comprehensive account of the correlation of the British Ordovician and its Irish counterpart both nationally and internationally, and provided a standard reference for the system which has been widely followed. For the reader concerned with the origin and history of British stratigraphic names Williams et al. (1972) will remain the necessary reference. In the last 25 years, however, there has been much new work on the type Ordovician and related successions in Britain and Ireland, and the time has come for a revision of its correlation (Whittington et al. 1984; Fortey et al. 1991, 1995). This has proved a major undertaking, not least because the Ordovician is probably the most complex System in the British Phanerozoic.
Figures & Tables
This Report is revised and expanded from the 1972 publication providing an up-to-the-minute account of the British Ordovician formations and their correlation nationally and internationally. It also includes the most comprehensive treatment of Ireland ever attempted. The reference list of a comprehensive bibliography of papers on the subject published since 1970.
The British sections are the type for the Ordovician System and classical in stratigraphical, tectonic and volcanic studies. The Charts bring together 30 years of research over the period in which plate tectonics has revolutionized our understanding of the Lower Palaeozoic rocks of the British Isles.
This Special Report will be a valuable reference for research and applied geoscientists working with rocks of Ordovician age. It will be of particular interest to those working in, or visiting, the Welsh mountains and the English Lake District.
