them is buffered in a straightforward way for phengite substitution (the exchange

Clays, Muds, and Shales
It is not known when illite alters to phengite. As the K-Ar ages of the finer size
fractions are relatively constant through the entire anchizone (Fig. 7-51), it is
unlikely that there is any systematic conversion of illite to phengite through this
interval.

Phengite was in part replaced in margin by biotite. biotite. The transformation
keeps H2O conservation due to the same structural OH of the two minerals and
