Abstract |
The relation between the x-ray line profile and the nature of interstratification in interstratified chlorite/saponite has been investigated. The line profiles are calculated by electric computer base...d on the theory of KAKINOKI and KoMURA (1952). The calculation is made by taking into account the effect of the number of component layers and the breadth of slits of diffractometer. The structure models of interstratified chlorite/saponite used for calculation belong to a system of two component layers (chlorite and saponite layers) and Reichweite S=l and part into two types of interstratification: (1) Re-type: there are no pairs of chlorite layer-chlorite layer (CC) and/or saponite layer-saponite layer (SS) (2) Ra-type: there are all sorts of pairs (CC, CS, SC, SS) By comparison of calculated profiles of the two types, it is concluded that some peaks present in the patterns of Re-type are not recognized in those of Ra-type. Therefore, these peaks could be an indicater of the type of interstratification.show more
