Basin Sediments and Processes as a Physicochemical System
Sediments that have just been deposited, as was indicated in the first volume of this monograph, represent a system of substances internally out of equilibrium and capable of reacting with each other. By various chemical transformations these substances gradually produce a system in physicochemical equilibrium, and this system then becomes a rock. The stage of physicochemical equilibrium of the primary components of sediments under the thermodynamic conditions of the earth’s surface has long been called the stage of ‘diagenesis’. It is necessary to examine this stage of lithogenesis systematically and in detail. Attention will be focussed exclusively on subaqueous accumulations.
