就像用“砝码”标定“称”来测量物质质量一样,伊利石结晶度的测量也需要这样的“砝码”标定它的测量工具——衍射仪,从而能够进行伊利石结晶度的测量和对比。这个砝码就是伊利石结晶度标样或称伊利石结晶度国际标样。第2届Kübler-Frey国际研讨会伊利石结晶度圆桌会议就伊利石结晶度标样和近变质带的确定的问题进行了深入的讨论。会议一致认为,用伊利石结晶度标样校正X射线衍射仪是极为重要和必要的,没有进行标样校正的伊利石结晶度数据将被拒绝发表,经过伊利石结晶度国际标样校正后的伊利石结晶度数据才可用于近变质带的划分和国际对比。本文就伊利石结晶度测量的有关衍射仪类型与差别,衍射仪系统,测量条件,样品的影响和国际标样对仪器的校正等问题进行了分析研究。结果表明不同型号仪器,同型号仪器不同测量条件与状态,样品的不同制备方法都将影响伊利石结晶度Kübler指数的测量。指出只有使用国际标样才可校正测量的伊利石结晶度Kübler指数,从而达到消除偏差准确划分近变质带的标准和进行国际对比的目的。
Just as with the “weight” calibration “scale” to measure material quality, the measurement of the illite crystallinity also requires a “weight” to calibrate its measuring instrument - the diffractometer to enable Measurement and comparison of illite crystallinity. This weight is the illite crystallinity standard or illite crystallinity international standard. The 2nd Kübler-Frey International Symposium The Illiite Crystallinity Roundtable held an in-depth discussion on the determination of illite crystallinity standards and near-metamorphic zones. It was agreed that it is extremely important and necessary to correct the X-ray diffractometer with the standard of illite crystallinity. The data of illite crystallinity without standard calibration will be rejected. After the calibration by the international standard of illite crystallinity Illite crystallinity data can be used for the near metamorphic belt division and international comparison. In this paper, the types and differences of diffractometer, diffractometer system, measurement conditions, sample influence and calibration of instruments by international standard samples were analyzed and analyzed. The results show that different types of instruments, different types of instruments with the same measurement conditions and conditions, different preparation methods of samples will affect the degree of illite crystallinity Kübler index measurements. It is pointed out that the Kübler index of the measured illite crystallinity can be corrected only by using international standard samples so as to achieve the goal of eliminating the accurate classification of the metamorphic belt and making the international comparison.
