Mineral NIR Spectra

Mineral NIR spectra capture overtone and combination bands in the 700–2500 nm range — particularly hydroxyl, water, and metal–OH vibrations diagnostic for clay minerals, carbonates, sulfates, and hydrated phases. NIR reflectance measurements penetrate deeper than mid-infrared, making the technique ideal for drill-core scanning, remote sensing, and non-destructive analysis.

NIR mineral spectroscopy is foundational for orbital mineral mapping, hyperspectral geological surveys, and exploration drill-core logging. Browse mineral NIR reference spectra on SpectralBench — examine reflectance features, compare against field or laboratory measurements, and download data as CSV or JCAMP-DX for calibration models.
