This clay has been studied by Fourier transform methods, which show that it is a random interstratification of mica with montmorillonite, subject however to the limiting condition that montmorillonite layers are never contiguous. It is very similar to one of the mixed-layer clays from Kinnekulle, Sweden, described by Mrs. Byström. The “separation rule” is perhaps one of the factors conditioning the appearance of definite stages in the mixed-layer mica-montmorillonite sequence, as noted by Mrs. Byström.
