| [摘要]矿物光谱混合模型研究对于蚀变带蚀变矿物信息提取具有重要意义。本文基于目前两种主流的非线性光谱混合模型Hapke和Shkuratov模型，通过对两者特性的对比分析，提出了一种综合利用这两种模型进行矿物或岩石光谱混合模拟的思路,并针对斑岩型铜矿典型蚀变分带现象，进行钾化带、绢英岩化带、泥化带、青磐岩化带等典型蚀变带矿物组合光谱模拟实验。本研究提取结果可以为斑岩铜矿蚀变带研究提供理论依据。 |

| Abstract: Spectral mixture model for minerals plays important roles in extraction of alteration information. The Hapke and Shkuratov models are two important non-liner 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 spectral of typical mineral assemblages of the alteration zones (potassic, phyllic, argillic and propylitic zones), taking the alteration zones in porphyry copper deposits as an example. The results can provide a theoretical basis for studies of alteration zones in porphyry copper deposits. |
