Nagssugtoqidian tectonics at the western end of the Itivdleq shear zone, West Greenland

Abstract

From field work, centred around the settlement of Itivdleq, a pieture of the Nagssugtoqidian deformation in thjs area is presented (fig. 1). Major structure-forming movements occurred under high-grade metamorphic conditions (amphibolite-facies) and are divided into two stages. During the second stage a swarm of basic dykes, the Kangamiut dykes, were emplaced.
