Preliminary notes on the Tertiary lavas of northern Disko

Abstract

A study on the lavas of northern Disko has recently been started. V. Munther has kindly lent the writer samples of Disko lavas collected on the earlier Nugssuaq expeditions. Apart from the pioneering work by Steenstrup (1882, 1901) very little has been published on the lavas from this region. Extensive literature exists on the rocks containing telluric iron but cannot be cited here.
