Methods used to spatially locate features observed in the field (e.g. site/outcrop descriptions, structural readings, etc.), data obtained from legacy documents (e.g. airphotos, maps, previously published reports), or the position of exploration, mining and related infrastructure features. Each location method has a spatial accuracy that indicates the maximum estimated approximate error in the location.

A list of units of measurement (UoM) relevant for geoscience and the administration of statutory submissions from the resource industries. The list is based on the Geological Survey of Queensland (GSQ) Geoscience Profile of the Quantities, Units, Dimensions & Types (QUDT) ontology and vocabularies lists (https://linked.data.gov.au/def/geou and https://www.qudt.org/doc/DOC_VOCAB-UNITS.html - version 2.1.29).

The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves ('the JORC Code') is a professional code of practice that sets mandatory, minimum standards for Public Reporting of minerals Exploration Results, Mineral Resources and Ore Reserves, according to the levels of confidence in geological knowledge and technical and economic considerations.

This vocabulary lists the types of tectonic and lithotectonic units that are used to define the geological framework / 4D evolution of Western Australia and are relevant to the duties of the Geological Survey of Western Australia (GSWA). A tectonic unit is defined as a named mass/body of rock with defined geological characteristics (geological structure, sedimentary stratigraphy, magmatic activity, metamorphism, metallogeny and alteration) and evolutionary history different from that of surrounding/contiguous units.

Terms that describe the ratio of temperature to pressure (T/P) during metamorphism, defining a classification scheme based on thermal gradient that is regarded as the most appropriate for building a temporal geodynamic context for metamorphic data. Some of these terms only partly correspond to metamorphic facies fields and classic-style terminology such as Barrovian and Buchan (i.e. correspondence is not one-for-one).

Terms used to describe the stage of metamorphism of rocks based on the nature of the change in pressure and temperature conditions to which the rocks are subjected. Definitions are taken or derived from:
Fettes, D and Desmons, J (eds.) 2007, Metamorphic Rocks: a classification and glossary of terms — Recommendations of the International Union of Geological Sciences Subcommission on the Systematics of Metamorphic Rocks: Cambridge University Press, 244p.

Terms used to describe the sequence of pressure(P) – temperature(T) conditions that occurred in a given rock body over a period of time (t) of a particular metamorphic event. Also called P–T–t paths.

A metamorphic facies is defined by a repeatedly occurring and thus predictable set of stable mineral assemblages in metamorphic rocks. Such metamorphic mineral assemblages crystallize and are stable over a range of externally imposed physical conditions, most crucially lithostatic pressure and temperature, and thus the facies define areas in two-dimensional plots of pressure–temperature space. There is a demonstrable/proven relationship between mineral composition and bulk rock chemical composition and a consistent relationship through geological time.

Terminology defined by the Committee for Mineral Reserves International Reporting Standards (CRIRSCO; https://www.crirsco.com/) based on the International Reporting Template (IRT; https://www.crirsco.com/docs/CRIRSCO_International_Reporting_Template_November_2019.pdf). The IRT is a document that draws on the best of the CRIRSCO-style reporting standards, the JORC Code (Australasia), SAMREC Code (South Africa), Reporting Code (UK / Western Europe), CIM Guidelines (Canada), SME Guide (USA) and Certification Code (Chile).

The point or level from which heights and depths are measured and referenced to for an entity or activity. Typically these are expressed relative to a common global or regional reference datum such as the Australian Height Datum (AHD) or can be related to local reference systems. Specific emphasis is placed on elevation references used by resource exploration and drilling programs, whereby depths are measured relative to local reference datums or specific parts of a borehole/drilling platform. Concepts in this vocabulary include both reference datums (e.g.
