An interpretation of irregular dyke form in the Itivdleq shear zone, West Greenland

Abstract

Around the settlement of Itivdleq the general form of the Kangamiut dykes varies according to whether the intrusions occur within or outside the pre-dyke Itivdleq shear zone (fig. 1; Nash, this volume). Outlined below is an interpretation of the origin and development of the different dyke forms in the shear zone and some brief remarks on the significance of the results.
