At the U.S. Geological Survey, re- searchers use XRD to characterize geologic materials from a wide variety of settings. The interest in miner- alogy or minerals present is because characterizing the minerals in a reservoir stone can be an important aspect in determining and understanding of petroleum reservoir quality (Eslinger Pevear, 1988).

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.

Typically, powder X-ray diffraction (XRD) is an average of randomly oriented microcrystals that should equally represent all crystal orientation if a large enough sample is present. X-rays are directed at the sample while slowly rotated which produce a diffraction pattern which show intensity of x-rays collected at different angles.
