Abstract. To quickly identify mineral pigments in Dunhuang murals, the spectral matching algorithm (SMA) containing four methods was combined with laser induced breakdown spectroscopy (LIBS) for the first time. According to the similarity values between the two types of the same pigment sample, the optimal range of LIBS spectrum suitable for mineral pigments was determined. A mineral pigment LIBS database was established by comparing the spectral similarity of tablet and simulated samples, and this database was successfully used to identify unknown pigments on tablet, simulated, and real mural debris samples. The above results show that the SMA method coupled with the LIBS technique has great potential for identifying mineral pigments.
