A palaeomagnetic study has been made on Vendian-Early Cambrian rocks o
f the Tanafjord and Vestertana groups from the Varanger Peninsula, nor
thernmost Norway. Magnetic components of probably primary origin were
isolated at two sites apparently unaffected by the Finnmarkian-Scandia
n events of the Caledonian Orogeny. Sites situated in the Caledonian G
aissa Nappe or close to its front were remagnetized and comparison wit
h a tentative Ordovician to Devonian apparent polar wander path indica
tes that the remagnetization occurred during these periods.
