3D geological model of the Pukekohe area [explanatory text]

The ‘3D Geology of the Pukekohe area’ is a component of the GNS Science Geological Map 12 product suite and accompanies map compilations of the geology and geomorphology of the Pukekohe area. The 3D geological model is a visualisation of the near-surface and subsurface geology, including basement rocks and the thickness and geometry of geological units overlying basement and major faults.

The 3D geological model provides a generalised representation of the subsurface geology extending from the southern shoreline of Manukau Harbour to the lower Waikato River valley. The main features of this 3D geological model include a representation of the underlying block-faulted Mesozoic basement and basin geometry of the Pukekohe area, contacts and thicknesses of the Te Kuiti Group, Māui Supergroup (Waitematā/Waitākere groups), Ōtāhuhu Member (Takaanini Formation) and ‘undifferentiated Kaihu group’ with a depiction of the South Auckland Volcanic Field strata (Kerikeri Volcanic Group).

An explanatory text describing the 3D geological model can be downloaded via the icon link above. The 3D geological model is available for download and viewable using freely downloadable Leapfrog Viewer 3D visualisation software. 2D and 3D surfaces for use in GIS or 3D modelling software are also available download.
