The geochemical cycle of water includes percolation of atmospheric moisture into rocks and ends with the surface discharge of water regenerated from the deep-lying zone of regional metamorphism. Supergene alteration reactions are accompanied by dissociation of much groundwater. The two components of water, H+ and O2-, are separated by incorporation into different secondary products - H+ into clay minerals and O2- into carbonates - due to the corrosive action of the system H2O-CO2-endogenic aluminosilicates. The zone of metamorphism is a zone of active synthesis of H2O and CO2 molecules; groundwater accumulating there is enriched in CO2 and actively affects many geochemical processes including hydrothermal deposition. -S.R.
