抄録

An ANOVA (analysis of variance) method was applied for the estimation of the factorial effects on the transformation from dioctahedral mica to mica/smectite interstratified mineral. Two kinds of characteristic variables, the transformationratio and the profile broadness (crystallite size), were obtained from two different X-ray profile analyses. one of which was from the resolved individual profiles and the other from the unresolved ones. Both analytic results were in good agreement. However, the ANOVA for principal components of the unresolved profiles was more informative than for the characteristic variables of the resolved ones. The following results were noticeable; (1) the transformation ratio was largely affectedwith the specimen preheating temperature and the stirring of solution, (2) the line profile of the starting specimen narrowed its broadness with the increase of the transformation ratio, which was remarkably responsible for the stirring effect. Some transformation mechanisms between them were discussed.
