Geology of the Provinces of Canterbury and Westland, New Zealand : a report comprising the results of official explorations
Igneous Rocks
Igneous Rocks.
No igneous rocks have been found in this formation in the Provinces of Canterbury and Westland, so that the volcanic disturbances which we were able to trace in the formations previously described had already ceased in this part of New Zealand. However, Captain Hutton believes that both in the North and South, in Marlborough, and Otago, volcanic action was not dormant during the deposition of the Pareora formation. He refers the basaltic tufas between Lyndon and the Hanmer plains in Marlborough, and the basaltic rocks of Moeraki, to that period, both of which I consider, however, to be of greater age, and to belong to the Oamaru formation.
