Hawaiian Plume Magmatism Data for Isothermal Melting Analysis

Hawaiian-Emperor seamount chain data supports analysis of mantle plume temperature over 80 million years. The dataset contains olivine-hosted Cr-spinel and melt inclusion measurements from primitive lavas, compiled by Nikolai Nekrylov. It is stored in an XLSX file sized at 583.4 KB.

Use Cases

• Modeling mantle potential temperature based on Cr-spinel and melt inclusion chemistry.
• Reconstructing paleo-magmatic conditions for the Hawaiian-Emperor chain over 80 million years.
• Comparing plume-derived magmas to surrounding mantle compositions.
• Calibrating geothermometers using primitive lava samples.

Strengths

• Includes data spanning an 80-million-year time range for longitudinal analysis.
• Focuses on primitive lavas and specific mineral phases (olivine-hosted Cr-spinel) for high-fidelity source signals.
• Released under a permissive CC-BY-4.0 license for open reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (583.4 KB), indicating limited scope.
