Mineral FTIR Spectra

Mineral FTIR spectra capture mid-infrared absorption fingerprints of naturally occurring inorganic solids — diagnostic Si–O stretches in silicates, sharp carbonate doublets in calcite and dolomite, hydroxyl bands in clays, and sulfate features in gypsum and alunite. These absorption patterns allow rapid, non-destructive identification of minerals in hand specimens, drill core, and powdered samples.

FTIR-based mineral identification is central to geological surveys, mining exploration, cement and ceramics quality control, and environmental site assessments.
