I.—On Olivine Nodules in the Basalt of Calton Hill, Derbyshire

Published online by Cambridge University Press:  01 May 2009

Extract

The object of this paper is to place on record the occurrence of olivine nodules in a British basalt which, though closely allied in structure to some of the Tertiary basalts of the Continent, belongs undoubtedly to the Carboniferous age. Olivine nodules frequently occur in the Continental basalts and have been considered by some writers as inclusions of peridotites, but by others as segregations from the magma.
