Fossil Seismogenic Fault Magnetic Field Maps and Mineralogy Data

Submillimeter-scale magnetic field maps visualize fluid-rock interactions within a fossil seismogenic fault. The 766.5 MB dataset, published by Taizo Uchida in April 2026, combines magnetic microscopy images with paleomagnetic, rock magnetic, and microstructural analysis results. It demonstrates localized mineral reactions, including pyrite alteration and concentrations of high-coercivity minerals and magnetite.

Use Cases

• Train image segmentation models to identify cataclastic flow domains based on magnetic field maps.
• Analyze correlations between magnetic mineral distribution and microstructural deformation features.
• Model localized alteration processes like pyrrhotite formation and oxidation to goethite/hematite.
• Validate magnetic microscopy as a tool for visualizing fluid-related mineral reactions in fault rocks.

Strengths

• Includes submillimeter-scale magnetic field mapping for high-resolution spatial analysis.
• Combines multiple data types: JPG images and XLSX tabular data from paleomagnetic experiments.
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
