| 摘 要： | 对河北省昌黎县闫庄铁矿床的磁铁石英岩型铁矿石样品进行了光谱反射率测量,并与其铁含量进行了相关关系研究,研究结果表明,铁矿石中铁含量与850～900 nm的反射率均值呈现显著指数负相关关系,并从光谱编录入手,绘制了闫庄铁矿1个钻孔部分样品的光谱曲线与光谱彩色条码柱状图,与地质柱状图合并生成简单的光谱地质柱状图;研究证明,用岩心光谱反射率值去定量估算其铁品位是可行的,根据光谱曲线生成简单的彩色地质光谱柱状图非常有效,具有推广前景.

| Abstract: | The objective of this study was to examine the capability of reflectance spectroscopy to drill core logging of Yanzhuang magnetite-quartzite type iron deposit,in Changli county,Hebei province.Rock samples were collected for chemical analyses and spectral measurements.The results showed that the iron content was negatively correlated with the average reflectance of 850-900nm.Based on the spectral logging,the spectral curves and the spectral colored code column of some samples from a drill hole of Yanzhuang iron ore deposit were drawn.They were incorporated with the geological column to generate a simple spectral and geological column that is proved to be effective.It is feasible for core spectral reflectance to estimate iron grade of magnetite quartzite type iron deposit and high spectral core logging is worthy popularizing. |
