| 摘 要： | 基于岩石中蚀变矿物对近红外光谱的吸收原理,确定测量蚀变矿物最佳波长范围,采用数学和谱图学习方法对岩石中蚀变矿物进行定性和定量分析。通过蚀变矿物特征光谱,提取光谱参数,建立蚀变矿物与成矿关系模型。以采自福建紫金山矿区钻孔岩芯测量结果为例,说明近红外蚀变矿物分析法的可靠性,并得出结论。

| Abstract: | Based on the principle of near-infrared spectrum absorption by altered minerals, optimum measurement wavelength ranges for altered minerals were fixed and qualitative and quantitative analysis for altered minerals in rocks by near infrared spectrometer were accomplished with the mathematics and spectrum learning methods. From the characteristic spectra of altered minerals, spectral parameters were acquired and the models of relationship between altered minerals and ore-forming were established. The measured spectral data from the drilling rock cores in Zijinshan Diggings in Fujian province was given as an example to illustrate the credibility of the method and some conclusions on application of the method in altered mineral analysis were also given. |
