Planktic and larger benthic foraminiferids studied in thin section from a suite of dredge samples at two sites on the Marion Plateau, offshore Queensland, Australia. The data likely contains faunal assemblage information used to date carbonate platforms and subsidence events. The dataset is provided by Geoscience Australia Data and was last updated in 2026.
Use Cases
- Dating carbonate platform sequences based on foraminiferal assemblages described in the study.
- Reconstructing paleoenvironmental conditions based on the presence of shallow-water indicators like Halimeda and hermatypic corals.
- Analyzing regional subsidence history based on the age ranges of platform and cavity-fill sediments.
- Studying faunal reworking and mixing in sedimentary records based on the presence of reworked older faunas like Lepidocyclina.
Strengths
- Data covers a significant geological time range from the Early Miocene to the Pleistocene.
- Description provides specific biostratigraphic zones (N.18 and N.22) and inferred water depths (less than 50 m).
- Analysis distinguishes between two distinct sites (northern and southern) with different geological histories.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for computational analysis.
