Spectroscopic methods are a cornerstone of mineral studies. These methods have the capability to acquire information at multiple scales from atoms to molecules to chemical bonds, as well as to elucidate crystal structures, physical properties, and more.

This special issue addresses all aspects of the geosciences that focus on the investigation of mineralogical issues using the wide array of spectroscopic approaches. Such approaches include, but are not limited to, UV–Vis, IR, Raman, XAS, Mössbauer, EPR, NMR, MS, LIBS, Brillouin, and synchrotron-based spectroscopies as well as in situ and remote sensing spectroscopies. Contributions from investigations that involve other spectroscopic methods are also encouraged.

Spectroscopic research from all aspects of mineral sciences will be considered, including studies focused on sedimentary, metamorphic, plutonic, and deep Earth minerals, as well as applications to environmental issues, cultural heritage, gemology, soil science, planetary materials, meteorites, and more.
