In this paper we present poststack time migrated images of the Donbas Foldbelt (Ukraine) data. The unmigrated stacked section was generated after applying the common reflection surface (CRS) stack method. For this data, interpretation of the poststack time migrated section af- ter conventional common midpoint stacking was difficult in certain areas of the line. The main fault zone which emerges at the surface is not clearly delineated in the conventional migrated stacked section. We show that the CRS method when correctly applied gives enhanced stacked images in these areas. The CRS parameters are determined automatically from an automated search strategy. No stacking velocity model is required. Poststack time migration of the CRS images reveals additional reflectors and improved reflector continuity. More steep dip events as well as deeper reflec- tors are recognized. This give more information about the continuity of the fault system and enhance the inter- pretation in the identified zones of the profile.
