where it turns sovith-west and follows tlie fliinks of the Mount Arthur Range^ 

 contorting the strata in the Graham, Baton, and Wangapeka Eivers. One 

 branch runs south-east along the Sherry River,* and probably reaches the 

 alpine overthrust near Lake Rotoiti. The main fault is continued into 

 the basin of the Owen.f which river it follows to the junction of the 

 Mangles, thence crossing to the Matakitaki. The Tutakif fault leaves the 

 Motueka fault at the Owen, flanks the Murchison peneplain on the west, 

 into the head of the Tutaki, thence by the Glenroy junction along the 

 Warbeck and AVarwick Rivers to the Maruia. The Matirit fault, parallel 

 to the Motueka fault, shows itself in the Upper Wangapeka and probably 

 the Upper Crow, follows the Upper Matiri to the Maruia junction, thence 

 by Deepdale into Larry's Creek, and flanks the Victoria peneplain on the 

 west, reaching the alpine overthrust near Lake Haupiri. 



The Takaka fault§ follows the Takaka River for twenty miles, thence 

 crosses the range joining the Motueka fault near the Baton. The Karamea 

 faultll crosses the Momit Arthur tableland from the Takaka to the Leslie, 

 thence into the Upper Karamea ; it determines the course of the north and 

 south branches of the Mokihinui, thence to the Buller by way of New Creek. 

 The MaAvhera fault, ^ a direct continuation, flanks the eastern base of the 

 Paparoas, running to sea south of the Taramakau. A subsidiary parallel 

 fault to the west determines the course of the Orikaka and Blackwater 

 Rivers. The Inangahua fault** leaves the Karamea fault at New Creek, 

 flanks the western base of the Brunner Range and the foothills of Victoria 

 Range, reaching as far south as the Big Grey, v,^here its southern continu- 

 ation is overlain by Old Man gravels. The Ross faultft is a south-west 

 fault, flanking the western of the granite foothills from the Grey River to- 

 Ross ; it manifests itself at Koiterangi and Mount Greenland. 



The Aorere faultjl runs along the western shores of Golden Bay and 

 follows the Aorere, and thence by way of Brown's Creek across the Gouland 

 Downs. The Wanganui fault runs south-west through West Wanganui 

 Inlet, and a probable parallel fault determines the trend of the coast from 

 Cape Farewell to Rocks Point. The LoAver Buller fault §§ follows the 

 coast-line south-west from north of the Mokihinui, and skirts the higher 

 land fromx the Ngakawhau to the entrance of the Buller Gorge, thence to 

 the coast at the mouth of Fox's River. The Mount William fault] t|| flanks
