【摘要】 以桂西地区沉积型铝土矿布泉近红外光谱剖面为例，利用近红外光谱分析仪在良好地段进行NIR光谱剖面测量，并对岩石或土壤的蚀变矿物进行光谱测试分析，通过比对分析以建立典型区岩石或土壤光谱特征参数找矿模式，总结出基于近红外光谱分析技术的沉积型铝土矿遥感找矿标志：高岭石峰位移低值区与含Mg-OH矿物峰位移的高值区呈负相关；硬水铝石结晶程度越高则含H₂O矿物的半高宽越小。以此推断找矿有利地段，缩小找矿范围，取得了满意的应用效果。更多还原

【Abstract】 The near-infrared spectrum analyzer is used to measure the NIR spectrum profile in a good condition area to test and analyze the alteration minerals in rock and soil for an example of Buquan near-infrared spectrum profile at the sedimentary bauxite deposit in West Guangxi.The prospecting model of spectral characteristic parameters of rock and soil in typical areas is established.The remote sensing prospecting sign of sedimentary bauxite deposit based on near-infrared spectrum analysis technology is summarized according to the comparison and analysis.The low value area of kaolinite peak displacement is negatively correlated with the high value area of Mg-OH mineral peak displacement.The higher the degree of crystallization of diasporite,the smaller the half-height and half-width of H₂O bearing minerals.So the favorable areas can be inferred for ore prospecting in order to narrow the scope of ore prospecting area.It is satisfied to obtain a good application result on the basis of near-infrared spectrum technology.更多还原
