摘要：Salt-induced deterioration of architectural heritage is accelerated drastically in marine environments. This paper investigates the deterioration mechanism of the Shore Temple using various analytical techniques. Deteriorated and pristine stone samples were analyzed using X-ray fluorescence spectroscopy (XRF), thin section studies, and SEM in order to understand the deterioration mechanism. The meteorological and micro-climatic conditions of Shore Temple in the tropical Indian climate were studied, as they have played a vital role in the deterioration of the stone matrix. The sides of the temple that face the sea as well as the upper part of the temple show intense alveolarization and the stone variety was petrologically identified as “garnetiferous hornblende biotite granite”. The evaluation of results in terms of the efficacy of ethyl silicate consolidation of stone after desalination is very difficult due to continuous sea sprays. The compatible lime rendering evidenced in the shelter area and then scientifically examined during this study may be applied as a protective layer to safeguard and conserve the lone Pallava edifice on the seashore from deterioration in tropical and hygric saline conditions.
