This dataset represents the horizons present at or near the surface and comprises arcs with attributes describing the horizon name, lithology, contact relationships, geologic history and age. The dataset is part of the Geology of the Napier-Hastings urban area 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 both ContactView and GeologicUnitView and uses the appropriate CGI Controlled Vocabularies. The dataset is associated with Lee JM, Begg JG, Bland KJ 2020. Geological map of the Napier-Hastings urban area 1:75 000. GNS Science geological map 7a. Lower Hutt, New Zealand. GNS Science.
