18 dredge hauls of rocks and sediments recovered from the deepwater Gippsland Basin during the 1998 Franklin Cruise FR11/98. The study provides lithology, age, and paleoenvironment information for the basin, categorizing samples into Late Cretaceous volcanics, volcaniclastics, Neogene calcareous sediments, and Quaternary calcareous oozes. The data was collected by the Australian Ocean Data Network.
Use Cases
- Reconstruct paleoenvironments based on lithology categories (volcanics, volcaniclastics, calcareous sediments)
- Analyze the timing of Tasman Sea rifting based on inferred Turonian to Coniacian volcanic ages
- Model coastal and marine depositional environments using described sedimentary features (cross-lamination, ripple marks, trace fossils)
- Study the onset of marine conditions and basin subsidence using palynological age data (~90 Ma to ~74 Ma)
Strengths
- 18 dredge hauls provide a sample set from specific water depths ranging from 800 to 3800 meters
- Lithological categorization into four distinct rock types with inferred age ranges
- Sample locations were sited on seismic reflection profiles and morphological features
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Some rock ages are not directly dated but inferred ('may have been laid down during...')
