The surface deterioration of stone monuments or rocks for construction has been assessed by visual interpretation or chemical analysis as an indirect method for the specimen of similar rocks as those of stone monuments because sampling on the stone monument is not possible due to damages during sampling processes. Quantitative deterioration assessments using reflectance spectroscopy was performed as a possible improvement of conventional qualitative deterioration assessment. Clay minerals and iron oxides, products of deterioration and standard materials for deterioration assessment, are detected on Mt. Gwanak granite, Hongje-dong granite and granite block used in Hwaseong fortress. Continua are removed from reflectance curves to compare deterioration rate quantitatively and relative degradation degree maps of weathering products are produced. Finally, workflow process based on the existing procedure for measuring spectral reflectances of minerals in laboratory and anomaly detecting technique of remote sensing field is proposed for the deterioration assessment using reflectance spectroscopy.
