Abstract: There is specified structure and conditions of forming terrigenous diamond-bearing rocks within the territories of ancient platforms during the Preplatform, Protoplatform and Platform mega-stages of evolution. There are made conclusions about diamond placers and primary deposits potential. Stages of forming diamond-bearing rocks in the Phanerozoic are distinguished. The formation of dispersion halos of kimberlite indicator minerals varied in time on the Gondwana and Laurasia platforms. The exception is the Neogene-Quarternary stage, which manifested itself within all diamond provinces of the world. There are listed factors of forming commercial diamond placers during sedimentation of terrigenous diamond-bearing rocks.
