摘　　要：利用便携式短波红外光谱矿物测量仪(PIMA)研究了河南前河金矿区的蚀变矿物种类、相对含量。PIMA共识别出19种蚀变矿物,对相对含量大于5%的6种蚀变矿物,伊利石、多硅白云母、硬石膏、蒙脱石、绿泥石、方解石进行了矿物学填图,并将其与矿体形态和金品位进行对比,初步分析了蚀变-矿化带的变化趋势,探讨了矿区深部的成矿远景。It is demonstrated that the portable infrared mineral analyzer （PIMA） is capable of deriving detailed mineralogical information on hydro- thermal alteration in the Qianhe gold mine, Henan. Nineteen alteration minerals is identified by PIMA, in which the relative content of six minerals are more than 6%, including iUite, phengite, anhydrite, montmorillonite, chlorite, calcite. With the geological mapping of these minerals comparing with the shape of orebodies and gold grade, alteration zones are initially divided, and prospect area is predicted.
