Major and trace element compositions for dolerite sills and dikes (Ferrar Dolerite) and basalt lava flows (Kirkpatrick Basalt) from the Ferrar Large Igneous Province. The dolerite data come mainly from sill samples in the central Transantarctic Mountains, while the lava data are from all principal extrusive rock outcrop regions. The dataset was aggregated by SCIOPS from NASA's EarthData platform.
Use Cases
- Classifying rock types based on major element compositions obtained by XRF.
- Modeling magmatic differentiation trends based on trace element data from ICP-MS.
- Correlating dolerite sills and basalt flows across regions using geochemical signatures.
- Investigating petrogenesis of the Ferrar Large Igneous Province based on combined major and trace element data.
Strengths
- Data includes both major and trace element compositions, providing a multi-element view.
- Samples cover two distinct rock types: dolerite sills/dikes and basalt lava flows.
- Geographic coverage includes multiple principal extrusive rock outcrop regions in Antarctica.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
