CAMBRIAN 169 The presence of limestone and quartzites in the above section, together withthe evident bedded structure of the schists, leads to the belief that most of themembers were ordinary clastic rocks that have been altered to a crystalline stateby the adjacent masses of g^ranite which have burst through the beds in the imme-diate neighbourhood of the last member of the section and which forms part of agreat mass of granite to the eastward. All the members are cut by large dykes ofcoarse white pegmatite and the pegmatization appears to have continued, on asmaller scale, in the deposition of felspar and quartz between the laminae of theschists to the production of the gneisses. Opposite the section on the north side ofthe river, there is an immense mass of granite, and further down stream the gran-ite is seen inclosing broken beds of the schists
