Abstract
The Gardar Province in southern Greenland is believed to have experienced three episodes of rifting, all associated with the extrusion of large volumes of alkalic magma. The available chronological data indicate that the Gardar Province was active for at least 200 m.y., from 1.35 to 1.12 Ga. It is difficult to reconcile this protracted history with plume models for the genesis of such alkaline flood-basalt provinces. -from Authors
