What reading level is South African Geology book?
To quickly assess the difficulty of the text, read a short excerpt:


A dyke may in its course come so near the surface that the impelling force behind it is able to lift up the cover of rocks, and hence a large dome-shaped chamber becomes formed, into which the liquid rock pours and solidifies. At other places the solubility or fusibility of the rocks is more at a particular place than at others, and here the same bulging of the dykes occurs, owing to the liquid magma eating out a great chamber for itself. These expanded dykes are called laccolites.
A laccolite
...may be a single solid expansion of lava, as in the dolerite laccolites of the Insiswa at Mount Ay lift', Mount Currie, and several others on the Drakensberg plateau; smaller ones are to be seen at Cradock and Burghersdorp. Another form is where the central ex- pansion is solid, but round the edge is a fringe of con- TECTONIC GEOLOGY 115 centric dykes intruded into the sedimentary beds, which they have not had sufficient energy to convert into liquid rock. Such a case is presented by the biggest laccolite, bar one, in the world, the Bush veld laccolite in the Trans- vaal, which is 250 ml.
