Radiometric Age of the Devonian Polar Shift relative to Europe

Abstract

PALAEOMAGNETIC surveys of Devonian rock formations in Europe have revealed two groups of poles1,2 separated by an angular distance estimated at about 35°–45°. The two polar regions correspond to formations which have been geologically assigned respectively to (i) the Lower Devonian and (ii) the Middle Devonian-Lower Carboniferous.
