Basing upon paleorekonstruktions of Subperethetys evolution Middle-Novopetrivka phase, main condition of placers forming (tectonic, hydrodinamic, geomorphological and sedimentation) have been elaborated for Kharkiv-Sumy placers zone. The local scheme of placers forming has been founded for Krasnokutsk titanium-zyrconium deposit. This scheme is based upon the concept of placer forming material provision mainly by river by means of placer forming area directly neigh-boring to delta in the frames of two facial zones-coastal and marine shallow (shelf). The provision of placer forming matherial by lateral coastal streams and underlying sedimentation is also considered. Basing upon placers forming mechanism a set of criterions of placers prognosis in zonal scale has been developed: stratigraphic (the relation to Middle-Novopetrivka subsuite); facial (the foundation of two facial zones with pertinent ores characteristics), lithofacial (lithological types of sands), hidrodinamic (the availability of pertinent hydrodinamic conditions), paleotransportation (the presence of delta), paleogeomorphological and phases-sedimentation (the connection with sequence cycles of basin evolution with pertinent conditions of sedimentation).
