Alkaline picrites and basalts constitute 20–200 m of lava flows and hyaloclastites in the middle part of an ∼2 km thick succession of tholeiitic picrites and basalts formed during continental rifting of West Greenland around 60 Ma. The alkaline rocks, found only in northern Disko, have phenocrysts o...
