Reference Debyeograms of cast stone minerals

Abstract

In the field of geological and mineralogical work, X-ray measurements can have a wide and varied application. In X-ray measurements, there are several methods for studying crystalline matter. The main methods are: the Laue method, the crystal rotation method, the Debye-Scherrer-Hall method, or the powder method and the Bragg method. To determine a given mineral, it is necessary to grind it into powder, obtain a Debyeogram from it and compare it with the Debyegrams of known minerals that could be assumed to be a given mineral. Similarly, when determining the mineral composition of a mixture, a Debyeogram is obtained from it and this latter is compared with the Debyegrams of those minerals whose presence was expected in the mixture. It follows that to apply this method it is necessary to have Debyegrams of known minerals as standards, with which the Debyegram of the analyzed substance is compared. In each individual area of application of the X-ray analysis method, a whole series of standard Debyegrams for a number of suspected substances must be prepared. At present, it is necessary to begin compiling an identification of substances based on their Debye patterns, similar to an identification of crystals based on goniometric data.
