The aim of work - the substantiation of rational techniques for measurement the gas debits into the atmosphere using various sorbents; the estimations of exploratory informativity of the sorbed and exchanging forms of microelements existence in the oils and shelf bottom deposits (Cu, Pb, Cr, Ni); determination the possibility of capturing on sorbents for the metals-satellites of deep gases on the oil and gas bearing areas of DDD; determination the recent geodynamic activity effect on the gas microseeps. Based on the results of gas debit survey in the central part of Northern edge of DDD (Narizhnyansko-Scvortsivsko-Yuliivskiy polygon, 164 points of observations) the principles of the sorbents selection, the construction of devices for debit measurements and the rational survey condition substantiated. On the 11 samples of soils and 9 samples of moods the exchanging and sorbed forms of microelements existence determined. The distribution of Cu, Pb, Cr, and Ni in these forms had been analysed with taking into account the areas Holocene mobility as well as landscape features. For the shelf terrain Dniestrovska zone - i. Zmiyny the tendency to the elements forms balance change depending on the Holocene movements gradients and the sediments thickness discovered. For the soil sections of Northern edge of DDD from the elements forms distribution and the specific of their concentration on sorbents the possibility of existence the hydrocarbons indices Ni, Cr, Cu in the volatile compounds composition argumented that makes the methodical potential of litho- and gas geochemical exploration more wide. The reliability of gas microseeps measurements on the various levels of soil sections, the affect from the particular biochemical processes and recent geodynamic activity determined. The gas composition and sorbents effectiveness estimated. The difference between the oil and gas bearing areas and terrains without perspectives in the gas microseeps and accessory volatile metal-organic compounds had been outlined. The activated charcoal, molecular sieves, clynoptylolyte and other sorbents ranged according to their suitability for geochemical exploration. Resulting from the estimating investigations on the Dashavske and Oparske underground gas storages the tectonogeochemical interpretational model of the extreme gas haloes formation proposed. The Holocene movements regime affect on the intensiveness of the force gases migration from storages to the surface. The branch of utilization is geological prospecting.
