It was established that with convective heat and mass transfer in the region of the Krasnoleninskij swell (West Siberia), the pulsating lateral pressure regime used to contribute to interlayer water avalanche liberation from the Upper Jurassic-Lower Cretaceous smectites in the process of their hydromicatization. The resurgent (petrogenic) water constituted the basis of the hydrothermal solutions responsible for the processes of ultra-acid leaching, metasomatosis, hydrocarbon generation and migration.
