Sandy clays deposited during the Oligocene-Middle Miocene transgression preserve marine dinoflagellates extinct by the late Middle Miocene. The dataset likely contains stratigraphic and paleontological data from the Murray Basin, sourced via the Australian Ocean Data Network. It proposes correlations between the Mologa weathering surface and global sequence boundaries at 13.8 Ma or 10.5 Ma.
Use Cases
- Correlating regional unconformities with global sea-level events based on sequence boundary ages.
- Studying marine transgression and regression phases based on sediment descriptions.
- Analyzing biostratigraphic markers based on described dinoflagellate and pollen species.
- Mapping lateral facies changes between marine and fluvio-lacustrine sediments.
Strengths
- Description includes specific geological time references (Oligocene-Middle Miocene).
- Proposes correlations with published sequence boundaries (13.8 Ma, 10.5 Ma).
- References newly described pollen species Tetrapollis campbellbrownii.
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/temporal bias inherent to data_gov_au.
