Abstract Hapke photometric model is a useful tool for studying the spectra of mixed minerals. However, there are still some improvable things, and domestic research still lags far behind that of foreign countries. This paper focuses on the characteristics of surface minerals through 4 groups of spectroscopic tests in laboratory, and then discusses and points out the accuracy of the Hapke photometric model when simulating the spectra of mixed minerals. The mean of root mean square errors (RMSE) of the 4 groups by using IMSA model is 0.014 4, and the mean of correlation coefficients (R) is 0.994 7. The mean of RMSE of the 4 groups by using AMSA model is 0.008 4, and the mean of R is 0.994 4. These data suggest that IMSA model and AMSA model have a very high precision and can be a good means to simulate spectral mixture of mixed minerals. Nevertheless, the experiment results show that, when the mixed minerals contain biotite, the accuracy is not satisfactory, but the accuracy of simulation can be improved by adjusting the weight of biotite. Spectral shape of mixed minerals needs a specific analysis of compositions of the mixed mineral, for instance, a particular mineral which possesses a higher mass fraction in the mixed minerals may not play the leading role in the spectral shape, while the mineral of low reflectivity may play a more important role.
