Research output: Contribution to journal › Article › Communication

Abstract

A new occurrence of ultramafic alkaline rocks in the Kangerdlugssuaq district of East Greenland is briefly described and more detailed penological and mineralogical data are presented for a leucite ankaratrite, which consists of diopside, leucite, nepheline, alkali feldspar, magnetite and phlogopite. The presence of potassic rocks in this area provides important additional evidence for the rifted origin of the area. This is the first well-substantiated report of leucite from Greenland.
