TUNNELLING IN ROCK. CHAPTER 3: ROCK FORMATION AND GEOLOGY OF SOUTH AFRICA

This paper provides a general background to the origin and classification of rocks and of structural features of the rock mass which are of significance for tunnelling. It is presented under the following headings: composition of rocks; origin of rocks; geological classification of rocks; granular structure of rock materials; structural discontinuities in rock masses; effect of geological structure on tunnel stability; geological factors significant in tunnelling; and major stratigraphic units of South Africa. /TRRL/
