Abstract:
The elements, salt type, and crystal structure of salts in the soil samples of the Terracotta Warriors and Horses of Qin Shihuang Mausoleum were analyzed by XRF、XPS、XRD in this paper, The results show that the soil samples contain Na+，K+，NH+4，Mg2+，Ca2+，Cl-，SO2-4，NO-3，HCO-3 ions. The soluble salts and slightly soluble salts in the samples are mainly NaCl、NaNO3、CaSO4·2H2O、2CaSO4·H2O、CaSO4、Na2Ca5(SO4)6·3H2O. The structures of salt samples were found to be dependent on the locations and environmental parameters of the Terracotta Warriors and Horses of Qin Shihuang Mausoleum. Those results are provided with the important guiding significance to study the formation mechanism of salt damages of the earthen heritage sites and to create system of availably protecting, preventing and cureing those heritages.
