The Lizard-Start Problem

Published online by Cambridge University Press:  01 May 2009

Abstract

Two questions are discussed: what is the nature of the boundary between the Devonian rocks of the Meneage and of the Start area on the one hand, and the mica- and green schists to the south of them on the other; and are the latter also Devonian or older than Devonian ? The author gives his views on the boundary in both cases, and concludes that the mica- and green schists in both are of Devonian age.
