Luckily, there is yet another method for mineral identification-x-ray diffraction! In this article, we describe the x-ray diffraction (XRD) method and the XRD Laboratory at the New Mexico Bureau of Geology and Mineral Resources. These mystery minerals are typically poorly formed crystals or amorphous (lacking crystal structure), too small to see even with a hand lens or high-powered microscope, or a combination of the two. Every once in a while, someone will deliver a “head-scratcher” for mineral identification that we can’t figure out. Despite the numerous physical properties of minerals (color, luster, streak, crystal form, and cleavage), some samples are impossible to classify with the standard identification tools, such as the streak plate, scratch test, hand lens, and microscope. The types of minerals found in a rock or in different geologic settings can help geoscientists determine the geologic history of a region, the potential for developing economic resources, or the possibility of geologic hazards. Mineral identification is one of the most fundamental components of the geosciences. Many geological samples do not have well-formed crystals like these.
