Study of soil cover is particularly important for solving the occurred problems from implementation of infrastructure works of the roads. The soil cover is at the upper part of the Earth's crust and has distinct properties morphological, mineralogical, physical and chemical differences due to climate, relief, waters. The interrelatedness of the various geomorphological, climatic, hydrological and soil factors and the human factor, resulted in a wide variety of soils with specific and constantly evolving.

Carbonaceous overburden rocks carry a heightened metallogenic potential. The possibility of extraction of valuable metals from natural bitumens and overburden rocks of oil fields is considered. The results of mineralogical and technological researches of samples are presented. The analysis of sample has shown an increased content of valuable microelements in some objects. All samples contain carbon of varying degrees of metamorphism. The fact of simultaneous concentration of carbonaceous rocks by several microelem...
