Rock Dredge Collection from RV Investigator Voyage IN2020_V01

The Rock Dredge Collection from RV Investigator Voyage IN2020_V01 documents samples recovered between 10 January and 6 March 2020 across William's Ridge and the Kerguelen Plateau. The dataset provides detailed records of dredge locations, sample descriptions, lithologies, and curation information. It was documented by Dr. Robyn Gardner and Dr. Derya Gürer and is curated at the University of Tasmania.

Use Cases

• Constraining tectonic evolution based on recovered igneous and sedimentary rocks.
• Investigating hotspot magmatism based on sample lithologies.
• Analyzing crustal architecture based on detailed dredge location records.
• Supporting petrological, geochemical, and geochronological investigations based on sample descriptions.

Strengths

• Data collection occurred during a defined research voyage from 10 January to 6 March 2020.
• Samples target specific geological features: William's Ridge and the Kerguelen Plateau.
• Dataset includes detailed records of dredge locations, sample descriptions, lithologies, and curation information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific dredging locations.
