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 It represents a synthesis of existing published and unpublished mapping of the continent's geologyin a single geodatabase at a regional scale.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).DOI https://doi.org/10.21420/7SH7-6K05

A raster ArcGIS grid that defines the elevation of the basal surface of the Heretaunga Formation geological unit. It has been derived from the 3D geological model of the Napier-Hastings urban area which forms part of GNS Geological Map 7. The 3D model was built using Leapfrog Geo software. This dataset forms part of Begg JG, Jones KE, Lee JM, Tschritter C. 2022. 3D geological model of the Napier-Hastings urban area [digital data]. Lower Hutt (NZ): GNS Science. (GNS Science geological map; 7b). https://doi.org/10.21420/JJEC-J652. The explanatory text associated with this dataset is available from https://doi.org/10.21420/QFEK-9369.

The layer defines the elevation of the top surface of the Christchurch 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 collection of raster ArcGIS grids that define the elevation of the top of basement and the elevation of the base and top, together with thickness, of the overlying geological units. They have been derived from the 3D geological model of the Pukekohe area which forms part of GNS Geological Map 12. The 3D geological model provides a conceptual three-dimensional representation and interpretation of the near-surface and subsurface geology including basement rocks, the thickness and geometry of geological units overlying basement and major faults.

The layer defines the elevation of the top surface of the Early-middle Quaternary geological units as a Gocad T-surf mesh. The layer has been derived from the 3D Eastern Canterbury Geological Model built using Leapfrog Geo software.

A collection of datasets related to the 3D geological model of the Napier-Hastings urban area that forms part of GNS Geological Map 7. The 3D geological model provides a conceptual three-dimensional representation and interpretation of the near-surface and subsurface geology including the thickness and geometry of stratigraphic and lithostratigraphic units, geometry of major faults, and drillhole and topographic data. The model has been developed in Leapfrog Geo software.

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

A Leapfrog Viewer File for the 3D geological model of the Pukekohe area which forms part of GNS Geological Map 12. It displays the subsurface volumes of stratigraphic and lithostratigraphic units, and associated drillhole and topographic data for the Pukekohe area. The 3D geological model was developed in Leapfrog Geo software and the file is to be opened with Seequent Leapfrog Viewer.
