This is the Geological Map of New Zealand (Chatham Islands) dataset collection produced by GNS Science. A Chatham Islands-specific NZGD2000 Transverse Mercator (EPSG:3793) projected coordinate system is used for these data that are east of the 180° meridian. The mapping frame within which the features have been observed is typically 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, where relevant, and uses the appropriate CGI Controlled Vocabularies. This collection 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). https://doi.org/10.21420/5XTJ-5718.

This dataset represents the faults present at or near the surface and comprises arcs with attributes describing the type of fault, its name, age and activity, and the sense of movement and cumulative slip. The dataset is part of the Geological Map of New Zealand (Chatham Islands) collection produced by GNS Science. The mapping frame within which the features have been observed is typically 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) but the mapping frame for some concealed features is bedrock (i.e. the solid rock that may either be exposed at the topographic surface or covered by other unconsolidated deposits). The data structure complies with the GeoSciML 4.1 standard for ShearDisplacementStructureView 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).

This dataset represents the textural metamorphic boundaries present at or near the surface and comprises arcs with attributes describing the type of contact, its accuracy and exposure. Textural metamorphic boundaries apply only to Late Paleozoic-Mesozoic greywacke terrane rocks. The dataset is part of the Geological Map of New Zealand (Chatham Islands) 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, where relevant, and uses the appropriate CGI Controlled Vocabularies. This dataset forms part of Heron, D.W.

This dataset represents the metamorphic units present at or near the surface and comprises polygons with attributes describing the mineral metamorphism properties such as grade, mineralogy and age. The dataset is part of the Geological Map of New Zealand (Chatham Islands) collection produced by GNS Science.
