Kaolinite as a mineral characteristic of continental deposits is present virtually throughout all facies studied. However, variations in its composition during the early stages of diagenesis, as compared to those of chlorite, illite and mixed-layer clays, is of no special diagenetic significance. Because of this, it wUl not be discussed at this stage. 

The clay mineral spectrum is characterized by the paragenesis of dioctahedral chlorites exhibiting primary crystallochemical features with dioctahedral illites sometimes containing swelling layers. This association is quite typical for continental deposits or those from brackish-water basins. In addition to chlorites with a stable structure we also observe swelling chlorites which are unstable on heat treatment and which occupy a sort of intermediate position between chlorite and vermiculite. It appears to represent a process of incomplete crystallization of minerals of the chlorite-vermiculite group in continental basins or under freshwater to brackish conditions. The minerals may thus be considered as metastable intermediate forms.
