| The Internal Cause of the Erosion in "Pisha" Sandstone Area, Southern Inner Mongolia |
| The rock and soil erosion in Pisha sandstone area of southern Inner Mongolia has been very serious. Its external causes are local atrocious climate and awful nature conditions, whereas its internal cause seems to be the existence of abundant erodible materials—“Pisha” sandstone. The intrinsic cause for the erosion of “Pisha” sandstone has been tentatively analyzed in this paper in the light of minerals, chemical compositions, rock associations, grain size distribution, structure characterstics and engineering features. |
