Until about 1960, geologists obtained mineral and rock analyses primarily using an approach called “wet chemistry.”. To obtain a wet chemical analysis, we can dissolve samples in acid and then analyze them by reactions involving precipitation, titration, or colorimetry.

The best method for mineral identification used by laboratories is X-Ray Diffraction (XRD). In XRD a small sample of the mineral the size of a grain of rice or smaller, is sent to a laboratory. The mineral is powdered and placed on a special plate that resembles a microscope slide. It is then put into a machine as big as a refrigerator.
