Basing upon paleorekonstruktions of Sub-Paratethys evolution Middle-Novi Petrivtsi phase, main conditions of placers forming (tectonic, hydrodynamic, geomorphological and sedimentation) have been revealed for Kharkiv-Sumy placers zone. The local scheme of placers forming has been founded for Krasnokutsk titanium-zirconium deposit. This scheme is based upon the concept of placer forming material provision mainly by river into placer forming area directly neighboring to delta in the frames of two facial zones coastal and marine shallow (shelf). The provision of placer forming material by lateral coastal streams and underlying sediments redeposition is also considered. Basing upon placers forming mechanism a set of criteria of placers prognosis in zonal scale has been developed: stratigraphic (the relation to Middle-Novi Petrivtsi subsuite); facial (the foundation of two facial zones with pertinent ores characteristics), lithofacial (lithological types of sands), hydrodynamic (the availability of pertinent hydrodynamic conditions), paleotransportation (the presence of delta), paleogeomorphological and phases-sedimentation (the connection with sequence cycles of basin evolution with pertinent conditions of sedimentation).
