蒙皂石—伊利石演化及有关问题的理论探讨

摘要：作者认为蒙皂石—伊利石的转化是多因素、多机制作用的结果．不同环境、不同机制形成的伊／蒙混层矿物，有序化出现时的伊利石层含量不同。伊／蒙混层由无序到有序是一个连续的渐变过程，存在过渡型混层矿物，多数伊／蒙混层矿物都是以某一类型为主的复杂集合体。作者指出分散蒙皂石是影响无序型伊／蒙混层矿物混层比计算精度的主要因素。

DISCUSSION ON SMECTITE ILLITIZATION AND RELATED PROBLEMS

he reaction of smectite to illite is controlled by multiple mechanisms and affected by many factors. I/S minerals formed under different geological conditions contain different amount of illite layers when their transition occur from random to ordered interlayerings.Smectite illitization is a progressive and continuous process, and intermediate phase may exist between the random and the ordered I/S phases. Most I/S minerals are probably a complex in which a certain type of interlayering dominates. Discrete smectite has important influence on the calculation of smectite layer percentage in randomly interstratified I/S minerals.
