Granite in a dry desert area is subjected to weathering and disintegration caused by thermal expansion and contraction of the rocks as a result of the extreme diurnal temperature variations in the hot dry weather. Powerful wind erodes weak points along joints and carries away the eroded materials. Sand carried by the wind also abrades the rock surface and eventually carves the granite surface on the windward side to become irregular and uneven. Honeycomb-shaped caves of varying forms and mushroom-like features are typical of this landscape. The Bortala Guaishigou Scenic Area in Xinjiang Province and Alxa Global Geopark in Inner Mongolia are typical examples.
