Distribution of soluble salts in the cliff strata of the Mogao Grottoes

Taking the salt distribution of the Mogao Grottoes cliff as the research object,this paper utilizes the classical solution chemistry method to study the occurrence of soluble salt such as sodium sulfate(Na2SO4),sodium chloride(NaCl) and calcium sulphate(CaSO4).Based on the analysis of the solution chemistry at different heights of the Mogao Grottoes cliff,the aqueous solution of the cliff rock is composed of a typical chemical composition and is of Ca.Na—SO4.Cl type.The composition of the Mogao ...
