The age and palaeomagnetism of Jurassic dykes, western Dronning Maud Land: implications for Gondwana breakup

New 40 Ar/ 39 Ar data from dykes intruded into Sverdrupfjella and Ahlmanryggen, Dronning Maud Land, Antarctica, indicate that dyke emplacement commenced at c . 207 Ma and lasted until c . 178 Ma.
