Bulletin No. 13, On the Geology of the Greymouth Subdivision, by 

 P. G. Morgan. . 



It is stated that here, as in other survey districts to the south, the 

 rocks of the main ranges, the so-called " Greenland series," have a 

 strike following the directions of the mountain range, viz., north-east to 

 Bouth-west. In the Poporoa Range, however, which lies close to the 

 west coast, the strike of the rocks is north-west to south-east. There 

 results are quite similar to those that have been obtained further 

 «outh, and Morgan ascribes the north-west strike to folding forces 

 exerted previous to the formation of the main range, that is later 

 Jurassic. In the Hohonu block of the main range there is a large 

 intrusion of granite, but its age is not indicated. Within this district, 

 Morgan states that further evidence exists in favour of the great over- 

 thrust fault that he believes forms the western boundary of the Alpine 

 Area. The question of the importance of this fault is not developed in
