摘　　要：本文利用近红外光谱分析仪在研究区进行近红外光谱剖面测量,选定研究区近红外光谱剖面Y001,对岩石或土壤的蚀变矿物进行光谱测试分析与反演,建立基于近红外光谱分析技术的沉积型铝土矿光谱特征参数找矿标志,从而推断找矿有利地段,缩小找矿范围,建立经红外光谱特征参数找矿模式。In this paper,the Near-infrared(NIR)spectrometric analyzer is used to measure the profile in the study area.Spectral analysis and inversion of altered minerals in the rock or soil were carried out.The near-infrared spectral profile Y001 was selected to perform spectral test and inversion of alteration minerals in rock or soil,aim to Establish Prospecting marks of characteristic parameters of sedimentary bauxite based on NIR spectral analysis technology,Thus,we can infer the favorable location of the prospecting,narrow the prospecting range,and establish the prospecting mode of the infrared spectral characteristic parameters.
