Soil-like formation in technogenic landscapes history of study, terminology, modern aspects (review)

E
Intensive mining and industrial processing are inevitably accompanied by withdrawal of agricultural and forest land from the turnover. Alienation of land under mining in Siberia is accompanied by loss of the most fertile soils. Within historically formed soil areas technogenic landscapes appear, most of them result from piles of waste rocks. Their surface is weathered, leached, and gets populated with biota over time. Soil-like bodies are formed of these mineral substrates. They are characterized by...
