  • Subsurface resistivity data is collected by the GNS by many different methods. These datasets are managed by the groups collecting and using the data, broadly based on acquisition method. The record is being used a master parent to group these resistivity dataset for ease of discovery

  • A database of geophysical logs derived from NZ boreholes (and derived velocity/time curves). It includes both digital and paper records

  • Magnetotellurics data are used to determine the subsurface electrical resistivity structure and image in 3-D the distribution of conductive regions within the Earth associated with e.g. geothermal fluids, magma, and shear zones beneath faults. Data have been collected across New Zealand (North and South islands), with large arrays measured the Taupo Volcanic Zone, Hikurangi Margin.

  • This collection of datasets comprise the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 data compilation. It contains the geospatial layers showing the main tectonic features and bathymetric environment of the region surrounding Te Riu-a-Māui / Zealandia.

  • This layer shows the interpreted location of spreading ridges, transform faults, and selected thrusts and other faults, in and around Te Riu-a-Māui / Zealandia. Ancillary information is provided about age, type of movement and plate boundary association. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

  • The Geology of the Victoria Range area (NZL_GNS_GM6_geology) comprises a 1:50 000 geological dataset covering part of the Buller District on the West Coast of the South Island of New Zealand.

  • This data layer spatially represents faults located at the surface or in Cretaceous-Cenozoic sedimentary rocks interpreted from seismic data. The dataset comprises arcs with each arc having attributes describing the type of fault, its name, age and activity, and the sense of movement and cumulative slip. The data structure complies with the GeoSciML 4.1 standard for ShearDisplacementStructureView and uses the relevant CGI Controlled Vocabularies.

  • Areas of similar magnetic character are identified by polygon features and described in terms of relative frequency and amplitude. This data layer contains interpretation of the total magnetic intensity reduced to pole aeromagnetic data from the Glass Earth geophysical survey undertaken in 2007. The data layer is part of the 'Geology of the Middlemarch area' 1:50 000 dataset covering a part of East Otago around Middlemarch township.

  • The extent and nature of landslide boundaries are represented by line features and described in terms of type and the accuracy with which the boundary is located. The data layer is part of the 'Geology of the Middlemarch area' 1:50 000 dataset covering a part of of East Otago around Middlemarch township.

  • This georeferenced raster image represents aeromagnetic data for the Middlemarch area depicting total magnetic intensity, reduced to pole, upwards continued to 500 metres. The data is part of a geophysical survey undertaken for Glass Earth NZ Ltd. in 2007. The data layer is part of the 'Geology of the Middlemarch area' 1:50 000 dataset covering a part of East Otago around Middlemarch township.
