Grindley, G.W.; Harrington, H.J.; Wood, B.L. 1959 The geological map of New Zealand 1 : 2,000,000. Wellington: New Zealand Geological Survey. New Zealand Geological Survey bulletin 66 111 p.
Abstract: A new geological map of New Zealand, presented on a scale of 1 : 2,000,000 summarises the results of geological mapping in New Zealand since the 1 : 1,013,760 map was published in 1947. The rocks of New Zealand are divided on this map into forty separate units. Twenty-three were used on the 1947 map. The chief differences are the mapping of many new igneous and metamorphic units, and closer subdivision of the pre-Mesozoic sediments. Advances have been made in mapping throughout the country, the most notable since 1947 being in North Auckland, Waikato, East Cape Peninsula, Wairarapa-Hawke's Bay, Marlborough, north-west Nelson, north and south Canterbury, western Otago and Fiordland. These notes outline these advances and validate stratigraphic names not previously defined in publications by the Geological Survey. To help the reader, a locality guide is presented showing the latitude and longitude of places mentioned in the text. (auth)
