From about 540 to at least 510 million years ago, sedimentation occurred in the Early to Middle Cambrian Stansbury Basin, with a distinct rift phase from 526 Ma. The dataset describes the basin's palaeogeographic zonation, structural evolution during the Delamerian Orogeny, and the potential for various mineral deposit types. It is hosted by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Modeling basin evolution and tectonic history based on described sedimentation phases and structural features.
- Identifying prospective areas for Mississippi Valley-type (MVT) mineralisation based on described unconformities, karst, and fluid conduits.
- Exploring for stratabound copper deposits based on redbed-to-marine transition zones mentioned for the shelf.
- Assessing potential for volcanogenic massive sulphide (VMS) deposits analogous to the Mt Read Volcanics beneath the Murray Basin.
- Evaluating structural controls on base-metal mineralisation in the Kanmantoo Trough based on described syn- to post-orogenic deformation.
Strengths
- Description provides specific geological time ranges, including sedimentation from about 540 Ma to at least 510 Ma and a rift phase from 526 Ma.
- Identifies specific geological structures and zones, such as the Kanmantoo Trough, Padthaway Ridge, and discrete shear zones on Kangaroo Island.
- Discusses multiple, specific mineralisation types and their geological contexts, including MVT, stratabound Cu, and VMS.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au, focusing solely on South Australia.
