Abstract
The hypergenesis zone processes are considered in regard to oxidation of metallic sulfides that deteriorate regional ecology due to transformation of hypogene sulfides in sulfate group minerals featured with high solubility and movability in the hypergenesis zone during summer monsoon in the coastal areas. The main agents of humid technogenesis are rainfalls rich in oxygen and other gases, that, with the help of the newly formed sulfuric acid, generate chemical oxidation and transformation of prime sulfides in oxidized groups of highly soluble sulfates.
