Method for in-situ nondestructive detection of stone sources of stone cultural relics

Abstract

The invention discloses a method for in-situ nondestructive detection of stone sources of stone cultural relics, which is used for detecting the stone sources of the stone cultural relics and comprises the following steps: determining potential sources of stones ofthe detected stone cultural relics through regional geologic features, historical records and the like; utilizing a portable X-ray fluorescence spectrophotometer to test chemical components of the detected stone cultural relics and stones of a potential source of the stone cultural relics; carrying out statistical analysis on the detected chemical component data by respectively utilizing a clustering analysis method and a Bayesian principal component analysis method; when the stones of the detected stone cultural relisc are matched with a certain potential source stone, obtaining the source of the stones of the detected stone cultural relics; and if the stones of the detected stone cultural relics is not matched with the potential source stone, continuously repeating the steps until the detected stone cultural relic stone is matched with the potential source stone. According to the method, the detected stone cultural relics are not damaged, sampling is not needed, the reliability is high, and in-situ detection can be achieved.

Description

technical field [0001] The invention relates to the technical field of cultural relics detection, in particular to a method for in-situ and non-destructive detection of stone sources of stone cultural relics. Background technique [0002] Stone cultural relics are an important form of preservation of cultural heritage in my country. With the passage of time, under the action of various natural forces, the degree of weathering of stone cultural relics will gradually increase, and they are in urgent need of protection and repair. According to the principle of restoring the old as old and minimal intervention, the stone used in the restoration of stone cultural relics must be the same as the original stone, so the research on the source of stone for stone cultural relics is of great significance. In addition, determining the source of stone cultural relics is also of great significance for cultural relics and archaeology. [0003] Historical records are an important basis for...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned research on the source of stone based on geological methods has some shortcomings: on the one hand, the above-mentioned methods need to first sample and prepare the samples of the stone cultural relics, and then conduct petrological characteristics research or geochemical tests on the samples, which is inevitable. It will cause damage to stone cultural relics. When the stone samples of stone cultural relics cannot be obtained, the above method will not work

On the other hand, the above-mentioned method is aimed at identifying the source of some specific stone cultural relics. The conclusion is that relevant experts judge based on petrological characteristics and geochemical data based on expert experience, and the degree of quantification is low, which leads to poor reproducibility of the method.
