【摘要】：敦煌莫高窟的部分壁画受到起甲、酥碱、疱疹等多种病害的破坏,病害的产生与崖体中盐分的运移有关,深入研究莫高窟崖体砂砾岩中盐分分布特征,对科学防治莫高窟壁画病害具有重要意义。通过对莫高窟第108窟西壁崖体砂砾岩中盐分和莫高窟崖体顶部以下20m深度范围内盐分调查,发现莫高窟崖体砂砾岩中盐分种类主要为硫酸盐和氯盐。整个崖体砂砾岩中盐分在大范围内分布较均匀,但在临空面出现了盐分集聚现象,在洞窟西壁和崖体顶部以下0.5m深度范围内盐分含量很高,平均为2.0%,最高为3.5%。本文首次从较深范围内对莫高窟崖体砂砾岩中盐分的分布特征进行了研究,这为以后莫高窟壁画盐害分析研究提供重要的数据支持。
[Abstract]:Some murals of Mogao Grottoes in Dunhuang were damaged by many diseases, such as A, soda, herpes, and so on. The occurrence of the diseases is related to the salt movement in the cliffs. The distribution characteristics of salt in the gravelly rocks of the cliffs of the Mogao Grottoes are deeply studied. It is of great significance for scientific prevention and treatment of murals in Mogao Grottoes. Through the investigation of salt in the sand gravel rock of West Wall Cliff of Mogao Grottoes 108 and in the depth of 20 m below the top of Mogao Grottoes, it is found that the salt species in the grit rock of Mogao Grottoes are mainly sulfate and chloride salt. The distribution of salt in the sand and gravel rock of the whole cliff body is relatively uniform in a large area, but there is a phenomenon of salt concentration on the face of the hollow. The salt content in the west wall of the cave and in the depth of 0.5 m below the top of the cliff body is very high, with an average salt content of 2.0. The highest value is 3.5. In this paper, the distribution characteristics of salt in grit rock of Mogao Grottoes are studied in depth for the first time, which provides important data support for the analysis of salt damage of murals in Mogao Grottoes in the future.
