EDS Analyses of Chromian Spinels in Conglomerate and Sandstone

Energy-dispersive X-ray spectroscopy analyses of chromian spinels from the Sanjissenzawa Fossiliferous Sandstone Member. The dataset includes derived geochemical indices such as FeO*, Mg#, and Cr#. It was authored by Aren Kanazawa and last updated on 2026-05-26.

Use Cases

• Provenance analysis of sedimentary rocks based on chromian spinel chemistry.
• Geochemical classification of spinel minerals based on derived indices like Mg# and Cr#.
• Correlation of detrital minerals between conglomerate and sandstone units.
• Assessing serpentinization processes based on mineral compositions from serpentinite blocks.

Strengths

• Data includes derived geochemical indices (FeO*, Mg#, Cr#) calculated from raw EDS measurements.
• The dataset is focused on a specific geological member and mineral type, providing a clear context.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
