This layer shows petroleum wells for which GNS has compiled graphical presentations of downhole well information such as lithology, stratigraphy, geochemical sampling and geophysical logs. It is a view based on the Petroleum Wells dataset and is updated spasmodically as new well sheets are created.

This dataset represents the sources used to compile the geological datasets. The dataset is part of the Geological Map of New Zealand collection produced by GNS Science. The dataset is associated with Heron, D.W. (custodian) 2020: Geological Map of New Zealand 1:250 000. GNS Science Geological Map 1 (3rd ed.). Lower Hutt, New Zealand. GNS Science. DOI: https://doi.org/10.21420/03PC-H178.

This dataset contains polygons showing the extent of swath (multibeam) bathymetry data in the SW Pacific. The dataset contains metadata for each survey, but not the actual swath bathymetry data. Data supplied by GNS Science, NIWA and LINZ, and sourced from international data repositories.

GERM - the GEological Resource Map of New Zealand database is a mineral deposit inventory of mineral, rock aggregate, building stone, coal, oil, gas, thermal water, and cold-water spring occurrences. More than 10,000 sites such as quarries, mines, dredges, wells, outcrops, seeps, springs, or fields are catalogued. Entries contain summary information on location, geology, geochemistry, exploration, production and use. The data were complied between 1983 and 1993, and published in a series of map sheets between 1984 and 1994. There has been no systematic update of the data since 1993, and therefore the status of some mining, quarrying and other extractive operations may have changed. Few new operations since 1994 are included in the GERM database. DOI:https://doi.org/10.21420/KZQD-G746 Cite as: GNS Science. (1994). New Zealand Geological Resource Map (GERM) [Data set].

This dataset has been superseded by a new edition (2nd edition, 2020) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/79DFDE2D-14C3-4E1A-9BAA-EE4AD2B545AB. This dataset is the supplemental geological boundaries data for the Geological Map of the Tongariro National Park area. The dataset is a product of the Geological Map of New Zealand project and was produced by GNS Science. It contains bounding contacts to geological units that are not included within the Geological_Boundaries dataset such those concealed beneath other mapped geological units and the limit of geological mapping (e.g where the geology is hidden beneath permanant ice). The dataset is stored in an ESRI vector geodatabase and exported to ArcGIS Server. The dataset comprises arcs with each arc having attributes describing the type of contact, its accuracy and exposure. The data structure complies with the GeoSciML 4.1 standard for ContactView and uses the relevant CGI Controlled Vocabularies.

Geological timescales are the frameworks that geologists use to assign ages to units of rock. This is probably one of the most fundamental concepts in geology and its allied fields, including paleontology and evolutionary studies. It is a basic requirement for many things, such as: • assigning geological age to rocks, fossils and economic minerals; • calibrating the rates of geological processes such as fault displacement and plate rotation, submergence, uplift and erosion of the land, earthquake frequency and volcanic activity; • measuring rates of climate change, sea-level change, biodiversity change and organic evolution; • the search for natural resources. Age indicators used to develop timescales are various, but the oldest and still most frequently used approach is to recognise rocks of similar age by the fossils they contain. The first geological timescales were developed in Europe, and these are gradually being consolidated into an international geological timescale which is expanded and updated every few years. Many areas of the world, however, have highly endemic fossils – just as countries like New Zealand have highly endemic plant and animal biotas today – and it is hard to relate the geology of these places to the international framework. Like many of these places, New Zealand uses the international scheme for the major units (Jurassic, Cretaceous, and so on) and for rocks which are not well represented in our own country, but adopts a more convenient local scheme, based on our own endemic fossils, for the smaller time divisions. Our New Zealand geological timescale has been under development since the earliest days of geological research in the country, in the late nineteenth century, although perhaps the greatest advances occurred through the 1940s to 1960s. A huge amount of related knowledge was collected together and published in 2004, in a monograph edited by Roger Cooper and published by GNS Science. Access is available online from the GNS Science web site. Like all scientific endeavours, timescales are continually revised as new knowledge comes to hand. Most commonly, these revisions apply to the absolute age calibrations of the time units. Although fossils are a useful way to quickly tell that two different bodies of rock are of similar age, they cannot – on their own – tell us exactly how old that is. Various events, such as the “first” (oldest) occurrence of a particular fossil shell, have to be calibrated using some technique, such as radiometric dating, to find out how many years ago the event took place. Unfortunately, calibration usually requires that numerous factors happen to be “just right” in order to be accurate. Consequently, new data comes to hand slowly, over many years.
