Research On The Relative Age Of Rock Art In Aletai By Means Of Nondestructive Spectral Analysis

Rock art is an indispensable kind of world cultural heritage in human civilization.The scientific research of rock painting is an exploration of human self cognition.The most difficult task in rock painting research is to judge the age of rock painting.By studying the relative age of rock paintings,it is to lay a theoretical foundation for judging the absolute age of rock paintings,and to trace the ancient human civilization tracks that are now missing in the torrent of time.Nondestructive exploration in the research development status of the relative age of Aletai in the first rock paintings from both at home and abroad for the rock dating method of spectral analysis,through the comparison analysis method to study the application in cultural relics,identified by spectroscopic analysis,archaeological stratigraphy and typology for research assistance.And after the pre feasibility demonstration and to measure its own difficulties in rock art field evaluation,combined with literature data,Japan Konica Minolta CS-2000 spectral radiance meter as spectral acquisition equipment was determined,using principal component analysis(PCA)as the target parameters for the data processing technology.Finally,the research work is summarized,and the existing shortcomings are pointed out,which shows the innovation in the study.
