<b>Abstract</b>— <p>Characteristics of soils of different ages in the rock lithology mosaic were identified for a unique ancient mining and metallurgical complex, recognized as a historical and cultural heritage site (Orenburg oblast). A comparative analysis of genetic properties of full-profile zonal soils and soils of various ages (buried and newly formed) was conducted in the technogenic landscapes of three mines in the Kargalinsky copper ore region. The geochemical characteristics of the parent rocks of different ages and their role in soil formation were determined. In the technogenic landscapes of copper ore deposits, rocks are represented by two main groups based on color and geochemical characteristics: red-colored and grayish-brown, with the highest copper content (up to 1.5%). A widespread group of gray and grayish-brown parent rocks exhibits geochemical similarities with red-colored rocks for 17 essential metals, they have higher copper concentrations (191 ± 45 mg/kg versus 81 ± 7 mg/kg), as well as those of phosphorus, sulfur, and barium, but lower concentrations of lead, chromium, and rubidium. For soils with humus horizons with higher copper contents than those in parent rocks (160 mg/kg), a positive correlation was found between copper, lead, and cobalt. The development of post-technogenic soils on waste rock dumps was limited by phytotoxicity due to the high content of heavy metals/metalloids of the first and second hazard classes, such as chromium, arsenic, copper, and nickel. Differences in the characteristic times of pedogenic processes over 34 centuries of soil development in technogenic landscapes were found. If the achieved efficiency of the humus profile process is estimated at 80% of the corresponding capacity of the virgin analogue, the geochemical maturity, which was diagnosed by the removal of mobile compounds, is estimated at 53%.</p>
