Abstract

Salt weathering is one of the important factors to weather the rock body at Mogao Grottoes. By a preliminary research on the property, mechanism and strength of salt weathering action, the paper proves that the Na2SO4, NaCl, MgSO4, CaSO4?2H2O, Ca(HCO3)2. are main materials to weather rocks in this area and points out the importance of moisture action in salt weathering process and sets forth the background of salt weathering in the rock. The purpose is to provide a scientific basis for the protection of the Dunhuang frescoes and the rock body of Grottoes.
