Cretaceous and Miocene Rock Samples from the Deepwater Gippsland Basin

18 dredge hauls were recovered from the deepwater Gippsland Basin during the 1998 R/V Franklin Cruise FR11/98. The study provides information on lithologies, ages, and paleo-environments, categorizing samples into volcanics, volcaniclastics, and calcareous sediments. The data was aggregated by the Australian Ocean Data Network and last updated in 2026.

Use Cases

• Modeling Late Cretaceous volcanic activity based on recovered basalt, hyaloclastite, and breccia samples.
• Analyzing paleo-environmental changes from Turonian to Campanian based on palynological age data and sediment descriptions.
• Studying Neogene marine depositional environments using recovered marly calcareous sediments and calcareous oozes.

Strengths

• 18 dredge hauls provide specific sample locations and depths.
• Samples are categorized into four distinct lithological and age groups.
• Ages are constrained by palynological data ranging from ~90 Ma to ~74 Ma.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the underlying research cruise was in 1998.
