The rocks to be described in this section comprise schist’s and gneisses collected from the moraines at Cape Denison. The terms" schist" and" gneiss" are used in a general way so as to cover those metamorphic rocks, /'both of igneous and of sedimentary origin, which display schistosity and' foliation.The more basic igneous types, the amphibolite’s and the calc-silicates, have already been described elsewhere. , All the rocks described in this section have been altered by Regional Metamorphism as defined by Harker, (1932, p. 177). Dynamic Metamorphism can be included in the scope of Regional Metamorphism as the lower limit in which pressure reaches its maximum and temperature its minimum.
