Summary
In the South Island the rocks deposited in the New Zealand Geosyncline of Late Paleozoic and Mesozoic age now form three main belts, non-schistose sediments lying both to the east and discontinuously to the west of a schist belt. For the non-schistose sediments of the eastern belt the name "Torlesse Group," derived from Haast's "Mount Torlesse Formation," which was used in a similar sense, is proposed. For the median schist belt the name "Haast Schist Group," named from the Haast River, is proposed, to embrace all the schistose rocks of the geosyncline.
