The ancient renovation activities of Yungang Grottoes: mutual verification of carbon-14 dating and archaeological investigation
摘要
Yungang Grottoes in Datong is one of the most famous stone cave temples in China. The caves have been renovated several times since they were first excavated by the royal family during the Northern Wei Dynasty (between AD 460 and AD 524), but few historical documents remain. On the basis of archaeological investigation, we collected some carbon-14 samples for testing by accelerator mass spectrometry (AMS) and used historical documents to study the ancient renovation activities of Yungang Grottoes. We found that there were different forms and scales of renovation activities during the Northern Wei, Tang, Liao, Jin, Ming and Qing dynasties.
