| 摘 要： | 利用光谱特征进行岩石矿物分析受到了国内外研究者的广泛关注，大多数蚀变矿物如赤铁矿、水云母等在可见光-近红外-短波红外波段具有诊断性强的波谱特征。因此，利用典型岩石矿物光谱特征可为矿产资源勘查与评价提供一种新的手段和方法。本文对相山铀矿田蚀变矿物进行光谱测量，经数据处理获得了不同典型蚀变岩石矿物的反射率光谱曲线。通过对这些光谱曲线特征的分析研究，提出了影响岩石矿物反射率的因素，探讨了水云母、萤石、赤铁矿等典型蚀变岩石的反射率曲线特征，并建立了相应的典型蚀变矿物光谱识别模型。

| Abstract: | Analysing rocks and minerals through their spectral characteristics has received wide attention from re searchers both at home and abroad, most of ahered minerals such as fluorite, hematite, hydromica have strong di agnostic spectral characteristics at near-infrared band. Spectral characteristics from typical rocks and minerals for exploreing and evaluateing mineral resources provides a new means and methods for geologists. This study meas- ui＇ed the spectrum Of altered rocks and minerals of Xiangshan uranium mineral field and obtained the spectral char acteristics of different type of altered rocks and minerals. In addition, the factors that affecting the reflectivity of rocks and minerals are analyzed. And the relationship between typical ahered rocks and minerals such as hydromi- ca, fluorite, hematite and their refleetivity are discussed. The spectral recognition models of typical altered rocks and minerals through researching on the spectral curves are developed. |
