Mineral Spectra

Minerals are naturally occurring inorganic solids with defined crystal structures and chemical compositions. This category covers silicates, carbonates, oxides, sulfates, phyllosilicates, and dozens of other mineral classes — the building blocks of rocks, soils, and ores that geologists, mining engineers, and environmental scientists encounter daily.

Mineral FTIR spectra and mineral identification through geological spectroscopy are central to fields ranging from exploration geology to gemology. Reference spectra allow analysts to match absorption features in unknown samples against verified standards, distinguishing between closely related minerals such as calcite and aragonite or differentiating serpentine polytypes. Accurate spectral libraries are essential for automated classification workflows in both laboratory and remote-sensing contexts.

On SpectralBench you can browse the full mineral reference collection, view interactive charts, and download each spectrum as CSV or JCAMP-DX for use in your own matching and analysis software. Use the comparison tools to overlay unknowns against these standards and identify your samples with confidence.
