This full color map illustrates at 1:250,000 the geology of the Wakatipu area, which compromises northern and Central Otago, and part of northern Southland. The map is part of a series initiated in 1996, which will cover the whole country. Onshore geology, offshore bathymetry, and major structural elements are shown, derived from published and unpublished mapping by GNS, MIWA, university and mineral exploration geologists. All geological map data are held in a geographic information ststem and are available in digital form, and as thematic maps at different scales. The accompanying illustrated text summarises the regional geology, tectonic development, economic geology, engineering geology and the potential geological hazards.
