The gravity field was reduced by replacing the gravity effect of the sediments by the effect of rocks 2,65 g/cm3 reference density. A computing complex cnabling the solution of a direct gravimetric problem from contact surfaces input to the computer by scanning was applied. With the 2,5-2,5 km network dinsity, the gravity effect of sediments including that coming from the local saline structures was calculated with great detail. In the obtained reduced field, anomalies of the Prypiat trough basement density inhomogeneities are clearly manifested. Zones of both low (mainly on the trough periphery) and high density of the basement were detected most intensive positive anomaly strikes submeridionally from the southern Chernigiv high of the Dnieper-Donets basin to the Volin' monocline in the western Prypiat' trough.
