Money Shoal Basin hydrogeological inventory

This Money Shoal Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

The Money Shoal Basin is a large passive margin basin in northern Australia, mainly located in the offshore Arafura Sea. Its sedimentary succession spans from the Mesozoic to the Cenozoic era, reaching a maximum thickness of 4,500 m in the northwest but thinner, less than 500 m, in central and eastern areas. The basin overlays the Neoproterozoic to Permian Arafura Basin and older Proterozoic rocks of the Pine Creek Orogen and McArthur Basin. It is bounded by the Bonaparte Basin to the west and the Carpentaria Basin to the east. The southern margin of the basin occurs onshore and is an erosional feature, although scattered remnant outliers of Money Shoal Basin rocks occur in isolated areas to the south and south-east of Darwin. The northern parts remain less explored, situated beyond Australia's maritime border with Indonesia.

The basin's Mesozoic sediments were deposited during passive margin subsidence, and consequently remain relatively undeformed. Compressional tectonics were later initiated during the Cenozoic collision between the Indo-Australian plate and Southeast Asia, causing minor structural disruptions along the northwest margin of the Australian plate. Most of the sediments in the basin were deposited in shallow to marginal marine environments, with minor evidence for short-lived episodes of deltaic and fluvial deposition in some areas. The sedimentary packages in the offshore basin are divided into four groups: Troughton Group equivalent, Flamingo Group equivalent, Bathurst Island Group, and Woodbine Group equivalent.

Onshore, the stratigraphic succession is limited to the Plover Formation equivalent, Bathurst Island Group, and the Eocene Van Diemen Sandstone. The Troughton Group extends from the Bonaparte Basin into western parts of the Money Shoal Basin, and chiefly consists of sandstone. The Flamingo Group, identified offshore, is considered equivalent to its Bonaparte Basin counterpart, characterized by sandstone and mudstone deposits, suggesting fluvial and deltaic settings. The Bathurst Island Group dominates onshore, composed mainly of fine-grained claystone, marl, and siltstone. The Woodbine Group is the uppermost unit, and is equivalent to the Woodbine Group of the Bonaparte Basin, consisting of Cenozoic deposits, primarily sandstone and claystone, indicating shallow marine and deltaic environments.

Statement

This document for the National Hydrogeological Inventory was created through the compilation and analysis of various national geospatial datasets and a range of supporting scientific and technical literature. In most cases, the spatial boundary (polygon) for the region was sourced from the Geoscience Australia Geological Provinces 2018 dataset. The geospatial data reported for the region of interest were selected by spatial queries of the region's polygon using Geographic Information System (GIS) applications. A variety of national-scale datasets were assessed for each region, with these data relevant to the study of groundwater, hydrogeology and related social, cultural or environmental characteristics. These data are published by various organisations (mostly Australian Government entities) and include fundamental Australian datasets such as the National Groundwater Information System (NGIS), National Aquifer Framework, Atlas of Groundwater Dependent Ecosystems and the Collaborative Australian Protected Areas Database (CAPAD). A complete list of all data used to develop the National Hydrogeological Inventory, and the various data processing and analysis methods used, will be released as part of a future Geoscience Australia publication focused on the hydrogeological inventory methodology.

The document also contains written summary information about the geology, hydrogeology and related features of the region of interest. These narrative summaries were compiled by Geoscience Australia researchers based on literature review and analysis of a range of scientific and technical publications about the region. The reports use similar document templates to ensure the consistency of information provided across the entire Australian continent.
