Investigation of agrillaceous rock properties by thermal analysis

Abstract

Background. The importance of studying the properties of argillaceous rock materials is determined by their widespread application in various industries. At the same time, identification of argillaceous minerals is associated with a number of difficulties.Aim. To study the properties of argillaceous rock materials collected in different sites by the method of simultaneous thermal analysis to reveal their characteristic patterns and to identify their composition.Materials and methods. Natural materials from different geographical sites in Russia and neighboring countries were studied by the method of simultaneous thermal analysis.Results. The use of simultaneous thermal analysis for studying the properties of argillaceous materials allows their behavior to be studied under temperature exposure. The composition of rock samples can be identified by comparing their thermogravimetric curves with those of known rocks.Conclusion. The possibility of using thermal analysis for identifying the presumed mineral composition of the studied rock material was established. However, the diversity of soils on the planet impedes drawing a definite conclusion about their mineral composition. Therefore, thermal analysis should be applied in combination with other research methods, such as XRD, sediment, optical, etc., analytical techniques.
