Explanation of Geological Map of New Zealand, prepared for Melbourne Exhibition.

Transactions and Proceedings of the Royal Society of New Zealand, Volume 13, 1880, Page 430

Dr. Hector exhibited and explained a copy of the geological map of New Zealand, which he had prepared for the Melbourne Exhibition, giving a particular account of the country geologically examined during the past year, and said that few were aware of the amount of labour and great hardships that had to be undergone in carrying on the survey in the more remote parts of the country. He gave a brief account of the progress of the geological survey from its commencement, and showed that by degrees we have attained a tolerably correct idea of the general structure of the whole country. There is still, however, a great deal to be done towards the accurate mapping of the formations, and particularly tracing those strata which indicate the presence of deep-seated coal seams, and the high level auriferous cements to which he had referred at the last meeting.
