摘　　要：本文介绍了利用傅立叶变换红外光谱仪测量矿物含量的方法。首先利用石英、长石、方解石、白云石、高岭石等14种沉积岩中的常见矿物制作了49组矿物混合物,这些混合物中各矿物的相对含量已知并符合各矿物在沉积岩中的分布规律。然后利用FTIR测量各组混合物中矿物的相对含量,结果表明该方法测量的误差在±2.6%以内。最后列举了2个利用FTIR方法进行矿物定量分析的实例,说明这种方法的精确性以及优势。This paper presents a methodology for obtaining quantitative mineral concentrations from transmission Fourier Transform Infrared（FTIR） spectroscopy.First,a set of 49 mixtures composed of quartz,feldspar,calcite,dolomite,kaolinite and other minerals which are common component of sedimentary rock.The relative concentrations of the minerals correspond to levels commonly found in clastic and carbonate lithologies.Secondly,the mineral mixtures were tested using FTIR,and the absolute difference between the known and derived mineral concentrations is ±2.6% wt.At last,two applications of quantitative mineral analysis by FTIR were listed.The accuracy of the method is examined.Major advantages for the proposed methodology are considered.
