Dating events in the Metamorphic Caledonides: impressions of the symposium held in Edinburgh, September 1971

Abstract

The symposium comprised seventeen contributions on the following subjects: palaeontological evidence for the age of the Dalradian, the Ordovician of western Ireland and other formations relevant to the dating of events (2 papers); the sequence of tectonothermal events in parts of the Moine Thrust Belt and the Moine Nappe (4 papers); deformation rates (1 paper); isotope ages and their relation to events in the Moinian and Dalradian areas (4 papers); early events in the Scandinavian Caledonides and their isotope dating (3 papers); and wider geotectonic aspects, including a plate tectonics synthesis (1 paper), a comparison of Newfoundland and Ireland (1 paper), and new palaeomagnetic evidence for the location of the main continental masses in the Palaeozoic (1 paper).
