Experimental Weathering of Weak Sandstone Without Direct Water Participation by Using Sandstone from the Yungang Grottoes in Datong, China.

The article focuses on the study conducted by the authors on influence of water on the weathering processes of sandstone by using Sandstone from the Yungang Grottoes in China. Topics discussed include deterioration of sandstone which begins from weaker points of the samples, changes in mineral composition of the samples such as quartz grains, feldspar and lithic fragments, and sulfates of calcium and magnesium salt.
