  • This collection of datasets comprises geological information for Antarctica. Data have been compiled by the GeoMAP team led by GNS Science. Version 2022-08 updates an early beta version (v.2019-07) in response to informal feedback and peer review, and/or the need for local improvements. GeoMAP has utilsed co-funding from GNS Science's Nationally Significant Databases and Collections Programme (NSDC) and international collaboration through the SCAR GeoMAP project(2015-2020). It represents a synthesis of existing published and unpublished mapping of the continent's geologyin a single geodatabase at a regional scale. The data comprises geological unit polygon geometry and attribute fields describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known and geological fault polyline geometry and attribute fields describing locational accuracy, exposure, fault type, and supporting background information, where this is known. Data are linked to the source polygon geometry which provides a spatial bibliography of key datasets and maps used in their compilation. The data structures within this geodatabase comply with the GeoSciML 4.1 standard where relevant and uses the relevant CGI Controlled Vocabularies. The GeoMAP dataset was produced as part of the Regional Geological Map Archive and Datafile, one of the Nationally Significant Collections and Databases supported by the New Zealand Government’s Strategic Science Investment Fund (contract C05X1701).

  • The layer defines the elevation of the basal surface of the Avonside Member geological unit as a Gocad T-surf mesh. The layer has been derived from the 3D Christchurch Geological Model built using Leapfrog Geo software.

  • The layer defines the elevation of the basal surface of the Bromley Formation geological unit as a contour ArcGIS shapefile. The layer has been derived from the 3D Christchurch Geological Model built using Leapfrog Geo software.

  • A Gocad T-surf mesh that defines the volume of the Murihiku-Dun Mountain-Maitai terranes geological unit. It has been derived from the 3D geological model of the Pukekohe area which forms part of GNS Geological Map 12. The 3D model was built using Leapfrog Geo software. This dataset forms part of Jones KE, Strogen DP, Hill MP. 2022. 3D geological model of the Pukekohe area [digital data]. Lower Hutt (NZ): GNS Science. (GNS Science geological map; 12a). https://doi.org/10.21420/PDRP-WS09. The explanatory text associated with this dataset is available from https://doi.org/10.21420/T65Q-MX18.

  • The layer defines the thickness of the Tertiary-Castlecliffian geological units as a raster ArcGIS grid. The layer has been derived from the 3D Eastern Canterbury Geological Model built using Leapfrog Geo software.

  • The layer defines the elevation of the basal surface of the Burwood Gravels geological unit as a Gocad T-surf mesh. The layer has been derived from the 3D Christchurch Geological Model built using Leapfrog Geo software.

  • The layer defines the volume of the upper silt component of the Christchurch Formation geological unit as a Gocad T-surf mesh. The layer has been derived from the 3D Christchurch Geological Model built using Leapfrog Geo software.

  • The layer defines the elevation of the top surface of the Riccarton Gravels geological unit as a raster ArcGIS grid. The layer has been derived from the 3D Eastern Canterbury Geological Model built using Leapfrog Geo software.

  • A Gocad T-surf mesh that defines the elevation of the top surface of the Ōtāhuhu Member (Takaanini Formation) geological unit. It has been derived from the 3D geological model of the Pukekohe area which forms part of GNS Geological Map 12. The 3D model was built using Leapfrog Geo software.
