Diamondiferous lamproites of Ingashi field, Siberian craton
Geological Society, London, Special Publications, 2021 Abstract Ingashi lamproite dykes are the only known primary sources of diamond in the Irkutsk district (Russia) and the only non-kimberlitic one in the Siberian craton. The Ingashi lamproite field is situated in the Urik-Iya graben within the Prisayan uplift of the Siberian craton.

А new ectasian event of basitic magmatism in the southern Siberian craton
Доклады Академии наук, 2019 On the basis of U-Pb dating of zircon and baddeleyite from gabbro-dolerite of the Goloustnaya dyke swarm (southern margin of the Siberian Craton), the age of basites was established as 1338.0 ± 2.9 Ma. It is shown that the basite intrusions of close ages from the Goloustnaya and Listvyanka areas (southern Siberian Craton) and Victoria Island (northern ...
