International standards and resources
We have not found an IUGS classification system for geological structures and landforms. A useful reference for this complex area of geology and physical geography is A geomorphic classification system, produced by the United States Department of Agriculture.
Australian conventions and resources
The Geoscience Australia website provides useful information, including a section on landforms and structures.
Many geological structures are named in the landscape, including tectonic plates, fault lines, seismic zones, cratons, provinces, basins, superbasins, domains, terranes and orogens. Use initial capitals for formal titles for these elements:
Australian Plate Pacific Plate Manus Microplate Tasman Fracture Zone San Andreas Fault Great Artesian Basin Baragwanath Transform Austral Petroleum Supersystem
Physiogeographic regions
Physiogeographic regions are areas mapped according to landform characteristics, and described in terms of landform, underlying geology, regolith (materials lying on bedrock) and soils. This classification is used in the Australian Soil Resource Information System (ASRIS). Seven main levels are described: division, province and zone (describe soils and landscapes across the continent); and district, system, facet and site (provide more detailed information from field surveys). Each lower level occurs within a higher-level category.
Use initial capitals for the names of physiogeographic regions:
Tasmanian Uplands Province Eastern Uplands Division West Tasmanian Ridges
