Three K/Ar age determinations have been made by O. L. on the lamprophyre dykes cutting the Precambrian crystalline basement in the Ravns Storø area of southern West Greenland. The samples were collected by Clark Friend and Lars Skov Andersen during GGU's regional team mapping programme. The petrology of the dykes is the subject of a special study by one of us (K. H.).
