Geochemical constraints on mantle melting during creation of the North Atlantic basin

Geochemical constraints on mantle melting during creation of the North Atlantic basin

Major- and trace-element data for lavas erupted during rifting of the Greenland-European continent about 60 million years ago are discussed. It is inferred that the earliest rift lavas can largely account for their high contents of incompatible elements.
