Bentonites are sedimentary rocks consisting clay minerals, such as montmorillonite (major constituent), beidellite
, saponite, nontronite, hectorite, and nonclay minerals (3).
Among expanding 2:1 layer silicates, vermiculite and beidellite
have a higher K fixation capacity than montmorillonite (Ross and Cline 1984).

The clay present is smectitic and probably beidellite
