Description
Gippsland Basin, Australia, was the site of 18 dredge hauls during the 1998 Franklin Cruise FR11/98. The study recovered volcanic, volcaniclastic, and calcareous rocks, providing lithological and paleo-environmental information for the deepwater basin. The dataset likely contains information on rock types, ages, and sample locations from seismic-guided dredging.
Use Cases
Classifying rock lithologies based on described categories like basalt, hyaloclastite, and calcareous ooze.
Analyzing paleo-environmental conditions from described features like burrows, trace fossils, and carbonaceous content.
Modeling basin subsidence and rifting history using age data from Turonian to Campanian palynology.
Studying the distribution of volcanic facies relative to the described continent-ocean boundary.
Strengths
Contains samples from 18 distinct dredge hauls with specific water depth ranges (e.g., 3300-3800 m).
Provides age constraints for samples, including Turonian to Campanian (~90-74 Ma) for some units.
Describes a clear categorization of recovered materials into four lithological groups.
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; last metadata update was 2026-04-30.
