Abstract: In the argillaceous fraction of a sedimentary series of petroliferous sandstones from the Sahara two successive diagenetic changes are considered. The first is kaolinization of the original silicates. This is followed by illitization of the kaolinite by saline waters. The same formation is kaolinitic where it produces petroleum and illitic where it is non-productive.
