| Abstract: | The formation history of dispersion halos of kimberlite indicator minerals in the Siberian Platform is described beginning from the main Middle Paleozoic productive epoch of kimberlite magmatism. The history and formation conditions of the halos are reconstructed from the ontogeny and typomorphism of indicator mineral assemblages with involvement of the geological history of the Siberian Platform. The general trend characterizing the development of indicator mineral halos is discussed. The data obtained allow adequate estimation of of the character and geological setting of indicator mineral halos for forecasting purposes. |
