摘要/Abstract

摘要： 根据衍射峰具有的不同分布特点推导出了14个伊利石结晶度K¨ubler 指数，Weaver 指数和Weber 指数关系式中常数项C 1-C 14的数值，提出了PearsonVII分布中形态参数μ 与C 5，C 6，C 11，C 12的4个定量方程。由此，14个伊利石结晶度指数关系式可直接用于实际计算。根据阿尔卑斯复理石伊利石形态特征Sc＝0.731，由这些关系式进行近变质带上下界线的转换得出与K¨ubler 指数0.42~0.25。△2θ 界线对应的Weaver 指数和Weber 指数的界线值分别为5.8~17.6和300~179。讨论了在自然干燥状态下直接进行伊蒙混层鉴定的基本原理。

Abstract: Constants C 1-C 14 in 14 equations of the relationships between the K¨ubler，Weaver and Weber indices were deduced and calculated. Four formulae of the relationships between exponent u of the Pearson VII function and C 5, C 6, C 11, C 12 were deduced also. Therefore, those 14 equations can be directly used for actual converting analysis. According to the shape parameter Sc＝0.731 for the XRD peak of illite from Alpine flysch and using these equations the boundaries of anchizone of Weaver and Weber indices were calculated as 5.8-17.6 and 300-179, respectively.Application in distinguishing illite/smectite mixed-layer phase in air-dried condition was discussed on the basis of the added principle of XRD peaks.
