Geoarchaeological methods were used to study chronosequences of surface soils in the steppe zone and to trace soil evolution during the Late Holocene in northwestern Crimea. It was found that the morphological and functional maturity of the humus horizons in steppe chernozems of the Late Holocene was reached in about 1600-1800 yrs. After this, their development decelerated irreversibly. The maximum concentration of trace elements accumulated in these horizons in the course of pedogenesis was reached in 1400 yrs. A new method of pedogenetic chronology based on the model chronofunction of the development of irreversible results of pedogenesis over time is suggested. Original pedochronological data and growth functions-the most suitable models for simulating pedogenesis over the past three thousand years-suggest that the development of morphological features of soil as an organomineral natural body follows growth patterns established for biological systems.
