The RRUFF project compiles high quality spectral data from characterized minerals worldwide with Raman Spectroscopy, X-ray Diffraction and Electron Microprobe.
Raman Spectroscopy compares their Raman spectral patterns to those from mineral samples that have been positively identified. X-ray Diffraction from powder and single crystal are used to identify and interpret the crystallographic characteristics unique to each mineral. Electron Microprobe analyses the chemical characteristics of each mineral.
The database may become a standard for gemologists, mineralogists and the general public for the identification of minerals. The database currently contains information on approximately 2000+ minerals with more added on regular basis.
The RRUFF™ project includes the research groups of Dr Robert T Downs (Geosciences, Arizona), Dr M Bonner Denton (Chemistry, Arizona), and Dr George R Rossman (Geological and Planetary Science, Caltech).
