in order; it extends in a narrow strip parallel to the schists and clay 
slates from Balclutha vié Switzers and the Eyre mountains to Martin Bay. 
There are also large areas between the Big River and the Monowai Lake, 
at Orepuki, Stewart Island, and the Upper Waitaki, with small patches 
at the Bluff, the Takatimos, Akatore, and the Horse Range. The Triassic, 
otherwise Maitai and Putaki formations, occupy the whole of the country 
between the Clutha and Mataura, as far inland as Gore, thence extending 
in an irregular chain to the Takatimo Range. The Waipai, or Cretaceous 
Formation, is represented in this Province by a strip of limited area, ex- 
tending from Shag Point to Otepopo, and asmall patch at Mount Hamilton. 
The Oamaru, Pareora and Wanganui series, corresponding to the Kocene, 
Miocene, and Pliocene of Geological Chronology, occupy portions of the 
coast from the Clutha to the Waitaki, including the Waitaki Plain. The 
Maniototo Plain, Ida Valley, Manuherikia Valley, and the Tokomairiro 
Plain, all belong to this group, and an irregular belt of the same runs 
from Orepuki to the head of the Te Anau Lake. The economic products 
of the Pleistocene Formation are chiefly clays, gravels, and sands, which 
will be considered further on. 
The voleanic rocks of Otago yield valuable building materials, and are 
situated chiefly between Saddle Hill and the Waikouaiti; but there are 
isolated patches at Aparima, Waihola, Upper Taieri, and between Shag 
Valley and Oamaru.

blendie granite, and pegmatite or congealed granite.
