Abstract:
To study the deterioration mechanism of open-air stone cultural relics in humid environments caused by soluble salt erosion, the cliff carvings of Shifosi in Chongqing were examined. Multiple analytical techniques, such as scanning electron microscope energy dispersive spectroscopy, X-ray diffraction, X-ray fluorescence, ion chromatography, and infrared thermal imaging, were employed to characterize surface deterioration and soluble salt types. Moreover, the study analyzed the effect of soluble salts on cave temples in humid environments, providing a scientific basis for preserving stone cultural relics.
