摘要：Initial soil formation on mining deposits. A preliminary report. A tailing pond of a lead and zinc mine in the Eastern Romanian Carpathians near Rodna was investigated for its features of soil formation and stabilisation. A series of orientated soil samples were taken and analysed for there structure and soil surface development. These samples exposed the phenomena of PSO (pellicular surface organisation) on the bare mining spoils, which are comparable to the soils development around sebkhas in seminarid regions. A biological organisation starts very soon. In some parts it already reached to the formation of an A h -horison and thus to the dynamic of forest soils such as rankers. The colonisation of grasses and Hippophae showed to best adapted to protect against deflation and linear soil erosion. Linear soil erosion on slopes is not an active geomorphological process yet. But the fragility of the system could occur, in case of aggressive pressure over the components of the system, the activation of linear and areal erosional processes.
