Extract

A comparison of the chemical features of Scottish magmas, has been greatly simplified through the appearance of a recent memoir, compiled from the records of the Geological Survey (Guppy, 1931). This memoir gives the composition, age, locality, and microscopic petrography of a great number of Scottish rocks. The present note deals with three Scottish magmas: Devonian (Lower Old Red Sandstone), Carboniferous and Tertiary. It excludes certain analyses of the Survey list, owing to decomposition of the analysed material. It includes a few from outside sources, to augment the data concerning the Devonian magma (F. Walker, 1924, 1925, 1927, 1928; and J. G. C. Anderson, 1935).
