摘要: Thermal analysis is a useful tool for determination of the rock‘s thermal behavior. The behavior rock affected by both its composition and structure. This study presents application thermogravimetric, differential thermal, thermomechanical analyses characterization selected Czech sandstone samples. detailed mineralogical was carried out FTIR spectroscopy, X-ray diffraction, optical microscopy. expansion during heating up to 1,000 °C, together with coefficient showed almost same values all studied Nevertheless, residual varied depending mainly on composition. In case higher content quartz, values. With increase carbonate, glauconite, or clay mineral volume, decreased. Factors such as grain size shape particles did not significantly influence observed
