ABSTRACT: - The process of pedogenesis on mine dumps (a case study: Aghireş mining area, Romania). The presence of mining, with all its specific activities carried on for decades, leads to an inevitable change in the evolution of environmental factors. Among these, and especially in the conditions of open-cast mining, the soil is definitely affected. The present study examines the soils developed on mine dumps in Aghireş mining area. It is noted that depending on how the mine dumps were managed, a differentially pedogenesis process started on their surface. Under these conditions, in order to determine the physical characteristics of soils in question, four sampling points were chosen, plus a fifth one with the role of control sample. The final results show clear differences between the physical parameters of investigated soil samples depending on the pedogenesis conditions, differing between the planted dumps and those without a protective vegetation cover.
