The similarity of flow structure of some lavas to the foliated structure of a schist was long ago pointed out by Darwin and Scrope, and recent work has proved that parallel structure due to differential movement prior to consolidation may be developed in plutonic rocks, as shown by Lieut.-General McMahon in the Himalayan granites, and by Lawson The Lovozero alkali massif, by K. A. Vlasov, M. Z. Kuzmenko and E. M. Eskova, translated by D. G. Fry and K. Sayers, edited by S. I. Tomkeieff and M. H. Battey.
The presence of aluminium in both the octahedral and tetrahedral sheets is essential to produce the similar a- and b-axis parameters that are necessary for the formation of a stable structure; an aluminium content of between 20 and 35 cation per cent is required for the best cell that results from this superposition of the octahedral and tetrahedral sheets has a ~ Å, b ~ Å, c The geological structure of these tracts of country is generally so complicated that it gives rise to much greater variety of outline than is to be found in either of the other types of scenery. Each kind of rock yields to the weather in its own characteristic way, and as the rainfall is heavier and the slopes steeper than elsewhere, the
