Gravity provinces and their nomenclature

Created 21/12/2025

Updated 21/12/2025

Gravity features have been defined and named by the various authors who have interpreted the results of land and marine reconnaissance gravity surveys in Australia. In general, two classes of feature have been identified - gravity provinces and gravity units. A gravity province is a region where the gravity field is characterized by uniformity of some property, such as contour trend, gravity level, or degree of contour disturbance, which distinguishes it from neighbouring provinces. A gravity unit is a subdivision of a province. Neighbouring units are again distinguished from each other by differences in contour trend, gravity level, or degree of contour disturbance - but on a smaller scale. Many gravity features were originally defined from the results of individual reconnaissance surveys in isolated areas and have been shown to be inconsistent with the regional gravity pattern after more extensive coverage has been obtained. Land and marine gravity coverage is now virtually complete, and an attempt has now been made to rationalize gravity province boundaries and names over the whole of Australia and its continental margins. In all, 125 provinces have been defined and named. It is recommended that authors make use of the names when discussing regional gravity features.
