But in Russia, ever since the pioneer studies of Polynov (1937), both kinds of mobility have been considered by landscape geochemists. Consequently, as the study of environmental geoch

Einleitung und Problemstellung, to the study of the circulation of elements in landscapes. More recently Kozlovskiy (1972) provided a series of conceptual models and principles, from the viewpoint of theoretical landscape geochemistry, that together summarize neatly the principal flow patterns of elements in landscapes.
