Stereoscopic radiography provides a simple and effective method to study ore textures in three-dimensions. The technique is based upon the same principles as stereoscopic vision and consists of taking two radiographs with different focal positions. When the resulting x-ray pictures are oriented in their proper relative positions and viewed under a stereoscope, a stereoscopic model is produced showing the three-dimensional relations of the size, shape, and orientation of the minerals within the specimen. Stereoradiographs of ore samples may be made with either a medical or industrial x-ray unit. Best results were obtained from specimens 1/2 to 1 inch thick exposed for 1 minute, 50 seconds at 3 milliamperes (330 MAS) and 70 kilovolts. The target-film distance may vary from 1 1/2 feet to 3 feet with an optimum stereoshift of 5 inches. Kodak industrial x-ray film type AA or type M produce the greatest contrast and sharpest detail. Exposure time, type of film and intensity of radiation, however, may easily be varied to enhance various textural features in different rock types. If care is taken in measuring thickness of specimen, focal- film distance, and stereoshift, photogrammetric instruments may be employed to measure directional properties of the ore fabric. This technique provides an entirely new perspective for the study of ore textures by allowing direct observation of the special arrangement of the component minerals. It is simple, inexpensive, and non- destructive and greatly supplements the type of data obtained by conventional microscopic techniques.
