The relationship between physical parameters, elemental content and spectral characteristics is not independent, which lays a foundation for exploring quantitative inversion methods of mineral contents and physical parameters of rocks through remote sensing information.This paper studies the relationship between spectra, physical parameters (density, magnetic susceptibility, resistivity, permittivity), metal contents (Fe, Ti, V, Mn, Zr, Co, Zn, Nb, Bi, Pb) of 590 rocks in Xingcheng Area. Correlates the physicochemical parameters with original spectra, spectral absorption depths, and high and low frequencies after spectral wavelet packet decomposition, finds out the characteristic bands of the physicochemical parameters affecting spectral absorption and reflection, and explores closely related parameters. This study lays the foundation for lithology classification of rocks, inversion of certain metal elements and physical properties, and prediction of closely related parameters with certain parameters. This article mainly achieved the following results. (1)The characteristic bands of Fe, Ti, Mn, V, Zn, Bi and Pb in igneous rocks are obtained. The Fe content of igneous rock is higher, and the correlation with spectra is more significant. Characteristic reflection bands of Fe exist near the 04 and 054 μm bands, and characteristic absorption bands exist in the range of 10～15 μm. In the range of 04～055 and 06～065 μm, correlations between Ti and the spectra are more significant. There is a characteristic absorption band of Ti near 228 μm band and a characteristic reflection band of Mn exists in 041 μm band. The correlation between spectra and V element of igneous rock is different from that of sedimentary rocks. Moreover, characteristic absorption bands of igneous rocks and characteristic reflection bands of sedimentary rocks may exist near 076, 081, 089 and 095 μm bands. The correlation between spectra and Zn content of sedimentary rocks is more significant than that of igneous rocks. There may be Zn characteristic reflection bands of igneous rocks near 041, 136 and 159 μm bands, and Zn characteristic bands of sedimentary rock near 234 μm band. In the vicinity of 214 μm band, Bi element has effects on spectra absorption of sedimentary rocks. The characteristic band of Pb may exist near 045, 054, 229 μm band. In the study of the relationship between physical properties and spectra of rocks, the density has significant spectral absorption and reflection characteristics in the range of 057～08 μm bands. Susceptibility makes spectra have strong reflection near the 053 μm band, and susceptibility gives spectra spectral absorption near the 108 μm band. Correlations between resistivities and spectra are similar to those between densities and spectra. In the correlation between various physical parameters of rocks, it is found that density is significantly positively correlated with resistivity. (3) In the relationship between various physical parameters of rock, it is found that density and resistivity are significantly positively correlated. (4) In the relationship between various physical parameters and metal elements of rocks, it is found that the correlation between density and metal elements is weak. The susceptibility is significantly positively correlated with Fe and Ti. The correlation between resistivity and metal elements is weak. The permittivity is positively correlated with metal elements. And correlations between V, Zn and Bi elements are the most significant. (5) There are significant positive correlations between Fe and Ti, positive correlations between Ti, Fe and V elements, and positive correlations between Zn and Pb.
