![]() If the sample is a mixture, XRD data can be analyzed to determine the proportion of the different minerals present. XRD can provide additional information beyond basic identification. XRD is particularly useful for identifying fine-grained minerals and mixtures or intergrowths of minerals, which may not lend themselves to analysis by other techniques. XRD provides the researcher with a fast and reliable tool for routine mineral identification. In many geologic investigations, XRD complements other mineralogical methods, including optical light microscopy, electron microprobe microscopy, and scanning electron microscopy. One of these methods, X-ray powder diffraction (XRD), is an instrumental technique that is used to identify minerals, as well as other crystalline materials. ![]() Numerous analytical techniques are used to characterize these materials. Rocks, sediments, and precipitates are examples of geologic materials that are composed of minerals. Examples of applications of this method to geologic studies are provided.
