抄録

Layer structures of regularly interstratified mica-montmorillonite (rectorite-like) were observed by high resolution electron microscopy. The specimens of regularly interstratified mineral used in this report were collected from the roseki (kaolin-pyrophyllite) deposits of Mitsuishi, Okayama Prefecture and Sano Mine, Kakuma, Nagano Prefecture.<BR>Lattice images taken from microtomed sections which were cut perpendicularly to the cleavage plane show the periodic structures with the spacing about 10Å along the [001] direction and with the spacing about 4.0 A crossing each other at an angle of about 70°.<BR>Lattice images of a curled edge show a periodic spacing with about 19.3Å along the [001] direction, and it is devided into two part, one of which is 10Å corresponding to a mica layer and the other is 9.3Å corresponding to a dehydrated montmorillonite layer.<BR>The ordering in the layer stacking of the interstratified mica-montmorillonite may differ in different occurrences.
