Zircon geochronology constraints on the geometry and solidification timescales of the Dufek layered mafic intrusion, Antarctica
The ~ 182 Ma Dufek Intrusion of Antarctica, associated with the Ferrar Dolerite Province, is a large layered mafic intrusion that is estimated to be similar in size to the 8–9 km thick Bushveld Complex of South Africa. Similar to the Bushveld Complex, the Dufek Intrusion displays a consistent stratigraphic progressio...
