摘要
Spectral mixture models for minerals play an important role in extraction of alteration information. The Hapke and Shkuratov models are two important non-linear spectral mixture models. This paper analyzes the characteristics of these two models, and puts forward a new method for simulating mixed spectral of mineral assemblages and rocks based on them. And we simulate the spectra of typical mineral assemblages of the alteration zones (potassic, phyllic, argillic and propylitic zones), taking the alteration zones in porphyry copper deposits as examples. The results can provide a theoretical basis for studies of alteration zones in porphyry copper deposits.
