This paper discusses stone relief images of four gods preserved as a Grade 1 National Monument at Lung Shan Temple, Lu Kang, Taiwan R.O.C.. The weathering of these four stone relief′s is severe due to loss of mineral compositions, formation of a weathered shell and stripped scales. When observed with a polarizing microscope, the thin weathered shell section was found to exhibit fiord shaped voids; When observed with a stereo microscope, the weathered shell was found to exhibit salt crystals on the weathered shell and void surfaces. SEM microscopy presented continuous mineral particle stripping. XRD examination showed that the gypsum exhibited salt crystals in the weathered shell. The results from this study will serve as a reference for subsequent preservation and conservation of stone cultural artifacts.
