The Gley Processes of Reduction in Epigenesis

  • Aleksandr I. Perel’man
Part of the Monographs in Geoscience book series (MOGEO)


The gley* forming processes are very common in soils, crusts, alluvium, and catagenetic subzones. Gley is formed in waters containing little, if any, hydrogen sulfide and no oxygen. Anaerobic bacteria thrive in such environments. They obtain their oxygen by breaking down different substances. Their waste products — carbon dioxide, methane, organic acids, etc. — are dissolved in water.
