Determination of Species and Relative Contents of Hydrothermal Alteration Minerals by Visible-Near Infared Spectroscopy

摘要: 采用可见-近红外光谱法鉴定热液蚀变矿物种类及相对含量.介绍了热液蚀变矿物的可见-近红外光谱吸收特征,采用可见-近红外光谱法和X射线衍射法对热液蚀变矿物样品进行分析.结果表明:可见-近红外光谱法在热液蚀变矿物种类鉴定方面与X射线衍射法分析方法结果比较接近.

Abstract: Visible-near infared spectroscopy was applied to the determination of species and relative contents of hydrothermal alteration minerals.Visible-near infrared absorption characteristics of hydrothermal alteration minerals were described.Samples of hydrothermal alteration minerals were analyzed by visible-near infared spectroscopy and X-ray diffraction.It was found that the species identification of hydrothermal alteration minerals obtained from visible-near infared spectroscopy was similar to those from X-ray diffraction.
