The roots of disagreement on the energetics of exogenous processes have been analyzed in the context of the modern views of water-rock interaction. Results of thermodynamic analysis of weathering reactions are reported. It is shown that the formation of supergene clays involves two different geological processes: hydrolysis of aluminosilicates and binding of large amounts of water. Relative to the bulk water, the bound water has a higher free energy of formation. This difference considerably changes the energetics of hydrolysis reactions, which actually are all endothermal. The conclusion is made that physically bound water and, therefore, clays bear large stocks of accumulated solar energy. This fact proves that oriented interior evolution and self-organization took place in inorganic matter and area similar to those known in biogenic systems, with genetic relationship existing between them.
