Summary

The distribution pattern of early diagenetic clay minerals such as kaolinite, smectite, palygorskite, glaucony and berthierine, as well as of mechanically infiltrated clays and mud intraclasts, is here predicted in siliciclastic rocks using a sequence stratigraphic approach. Changes in relative sea-level and in sediment supply/sedimentation rate, together with the climatic conditions prevalent during, and immediately after deposition of sediments control the type, abundance and spatial distribution of clay minerals by influencing the pore-water chemistry and the duration over which the sediments are submitted to a certain set of geochemical conditions. Diagenetic clay-mineral distribution is constrained along sequence and parasequence boundaries, and within parasequences, parasequence sets and systems tracts.
