VII.—On the Occurrence of Ottrelite in the Phyllites of North Cornwall

Published online by Cambridge University Press:  01 May 2009

Extract

The mineral ottrelite, which has received so much attention elsewhere, especially in the Ardennes, and which is of considerable interest in connection with the metamorphism of certain rocks, has not, up to now, ever been reported as occurring anywhere in Great Britain.

I am able to state that I have discovered it in considerable amount in a certain roofing-slate of North Cornwall.
