The Girvan–Ballantrae district is a classic Ordovician area that has played a key role in our understanding of the processes taking place along, or close to a destructive plate margin. The Ordovician rocks divide conveniently into two major associations: an older, northward-obducted ophiolite with associated volcanogenic and clastic sediments, and a younger, thick, transgressive cover sequence currently believed to represent a proximal fore-arc regime. Modern fore-arc sequences are commonly associated with fragments of obducted ocean crust, to which the Ballantrae Complex may be compared

A revised correlation of Ordovician Rocks in the British Isles
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.
