Abstract
Synopsis The chilled margin is of tholeiite basalt composition, and the chondrite-normalized rare-earth element pattern is almost flat with a slight light rare-earth depletion. The composition has affinities with a number of other rocks in the Tertiary Igneous Province including some of the Preshal Mhor type dykes, Skye, and is further evidence for the possibly important role of high-calcium, low-alkali, tholeiite magma in the generation of major intrusions in the Province.
