Palaeomagnetic Studies in the British Caledonides?VI Regional and Global Implications

Abstract

Palaeozoic palaeomagnetic data from the British Isles are reviewed and are found to be consistent with erratic polar shift from the vicinity of lo" N, 180" E in the Ordovician to 0", 145" E in the Siluro-Devonian and to 25" N, 160"E in the early Carboniferous. The Cambrian pole is less well established near 25" N, 170" E. The rates and times of shifts are discussed.
