...W. R. FITCHES; R. J. MUIR; A. J. MALTMAN; M. R. BENTLEY Abstract In the Scottish Caledonides context, the Colonsay-west Islay terrane has seemed anomalous and therefore likely to be allochthonous. New studies suggest, however, that its basement is not necessarily exotic but represents the missing...

...W. D. Urry; Arthur Holmes Abstract Part I by Urry discusses the helium method for determining the age of fine-grained basic igneous rocks and tabulates the results of examination of rocks of Shropshire, England, and Colonsay, Scotland (p. 45-48). In Part II Holmes discusses the geological relations...
