Abstract

The results of the comparative analysis of the primary impact diamonds from the Skal'noye deposit and yakutites from two placers of the Ebelyakh and the Dogoy rivers are presented. Studies were conducted to identify the main fea- tures of the impact diamonds formation in the Popigai astrobleme. Yakutites and diamonds from tagamites have im- pact nature. They are paramorphs on graphite of target rocks of the Archean gneisses. Diff ences between them are determined by the place of their formation. Yakutites were formed in the explosion epicenter and were thrown out of the crater at a distance of over 500 km in radial directions, and from the vertical ejection they got back to the crater. In tagamites, impact diamonds were formed simultaneously with the rock melting due to the shock wave that came from the epicenter
