The Early to Middle Cambrian Stansbury Basin preserves a palaeogeographic zonation from shallow shelf carbonates to extensional rift facies. Sedimentation occurred from about 540 Ma to at least 510 Ma, with a distinctive phase of thick rift sedimentation in the Kanmantoo Trough from 526 Ma. Granitoid emplacement accompanied compressive deformation and subsequent relaxation, with potential for Mississippi Valley-type and stratabound copper mineralisation.
Use Cases
- Mapping palaeogeographic zonation based on described carbonate shelves, rift facies, and back-arc basins
- Analyzing the timing of sedimentation and deformation based on the 540-510 Ma and 526 Ma events
- Identifying potential mineralisation zones based on unconformities, karst, porous carbonates, and reactivated thrusts
- Studying the association of base-metal deposits with flooding surfaces and manganiferous sea-floor exhalites
- Evaluating volcanogenic massive sulphide potential beneath the Murray Basin analogous to the Mt Read Volcanics
Strengths
- Description provides specific temporal ranges for sedimentation (540-510 Ma) and granitoid emplacement (510-500 Ma, 480-490 Ma)
- Description identifies distinct geological zones (Spencer Shelf, Kanmantoo Trough, Murray Basin) and their characteristics
- Description references specific mineralisation types (MVT, stratabound Cu, volcanogenic massive sulphide) and recent discoveries (Angas, Mt Torrens)
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
