An inventory of rock dredge samples collected during the RV Investigator voyage IN2024_T01 includes sample identifiers, collection metadata, and detailed macroscopic descriptions. Supporting imagery provides visual context for sample characteristics. The dataset is documented by the Australian Ocean Data Network.
Use Cases
- Classify mafic volcanic lithologies based on macroscopic descriptions of colour, grain size, and lithology.
- Analyze sample distribution based on collection metadata including location and water depth.
- Study mineralogy and alteration processes based on attributes like phenocryst abundance and groundmass texture.
- Identify and catalog manganese nodules and pelagic ooze based on the detailed sample descriptions.
Strengths
- Detailed macroscopic descriptions include standard geological attributes such as colour, grain size, lithology, mineralogy, phenocryst abundance, groundmass texture, vesicularity, and alteration.
- Links to associated photographic records and thin section data provide visual context.
- Samples are primarily composed of mafic volcanic lithologies (predominantly porphyritic basalts), providing a focused collection.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated 2026-05-05 00:36:50.330542.
