Description: This dataset represents the geological units present at or near the surface and comprises polygons with attributes describing the rock type, age and stratigraphic nomenclature. The dataset is part of the Geological Map of New Zealand (Mainland) collection produced by GNS Science. The mapping frame within which the features have been observed is defined as surface geology (i.e. the bedrock and superficial deposits that are exposed at the topographic surface or would be visible if the overlying soil was removed). The data structure complies with the GeoSciML 4.1 standard for GeologicUnitView and uses the appropriate CGI Controlled Vocabularies. This dataset forms part of Heron, D.W. (custodian) 2023: Geological Map of New Zealand 1:250 000 (4th ed.) [digital data]. Lower Hutt (NZ): GNS Science. (GNS Science geological map; 1).
