摘要
The Jing-shi-yu is located at a glacis in Taishan Mountain in Shandong Province, where a total of 2 799 Chinese characters for the Buddhism’s book entitled “The Vajracchedika Prajnaparamita Sutra” were written by caving on biotite quartz-diorite. Because of the long term natural weathering, freezing and scour, there are only 1 069 characters left. The view of the site and measurement shows that the multilayer sheet-like peeling on the diorite glacis is one of the main causes which has been destroying the cut in rock Chinese characters. Sheet-like exfoliation has reached the 5th layers. Each layer has a thickness of 0.5～0.8 cm. The geometric characteristics of multilayer sheet-like exfoliation is examined. A weathering model is put forward for the multilayer sheet-like exfoliation at the site. The model includes the process that the rock bulged firstly, then flaked off directly, or flaked off after the sheet-like due to bulging spreading through the rock.
