在哈密黄山铜镍矿区,采用 PIMA(便携式短波红外矿物分析仪)进行野外光谱测试,用新引进的 TSG(光谱地质专家)软件进行了矿物种类及相对含量识别、光谱处理分析,为蚀变矿物光谱分析起到了示范作用。详细论述了几类典型蚀变矿物的光谱特征；对绿泥石特征光谱吸收强度 D(Fe-OH )、D (Mg-OH)与矿物成分的关系进行了探讨。结果表明,绿泥石 Fe-OH 和 Mg-OH 吸收强度比值可以大体上代替 Fe2+/Mg2+比值,D [Mg-OH)/(Fe-OH)+(Mg-OH)]值绝大部分在0.4~0.8之间。用HyMap 数据做地质信息半定量反演,准确反映了各岩相主要金属元素含量的变化。研究结果对高光谱技术识别矿物种类、反演岩矿成分具有重要意义。

In Huangshan Cu-Ni deposit of Kumul,PIMA (Portable infrared mineral analyzer)is applied for field spectral test,and works such as identification of mineral species and relative content as well as spectral processing and analysis are conducted by using TSG (The Spectral Geologist)software.It demonstrates the spectral analysis on alteration minerals.This paper discusses in detail the spectral features of several species of typical alteration minerals.The relationship of diagnostic spectral absorption intensity D (Fe-OH)and D (Mg-OH)with mineral composition is also being discussed here.The result shows that Fe2 +/Mg2 + ratio of chlorite can be roughly replaced by Fe-OH and Mg-OH absorption intensity ratio,and D value [Mg-OH)/(Fe-OH)+ (Mg-OH)]mostly ranges between 0.4 and 0.8.The semi-quantitative inversion is conducted on geological information by using HyMap data,and the changes of major metal elements in various lithofa-cies are reflected accurately.The research has important implications for application of mineral species iden-tifying hyperspectral technology and rock composition inversion.
