Precambrian diamond crystals from the Siberian craton

Доклады Академии наук, 2019
Analysis of diamond grains from placers in the northeastern Siberian craton shows that some diamond varieties (round dodecahedra, varieties II and V-VII in the classification of Orlov) may originate from Precambrian sources. The Precambrian diamonds have different sedimentation histories.

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 ...
