Diamonds in old sedimentary rocks and their source (on the basis of Yakutia kimberlite province)

open access: yesРуды и металлы, 2022
This study provides the results of a complex investigation of a number of kimberlite bodies with half-industrial diamond content in several regions of the Siberian platform. This allowed us to establish the typomorphic features of the mineral.

Linking Siberian Traps LIP Emplacement and End-Permian Mass Extinction: Evidence from Magnetic Stratigraphy of the Maymecha-Kotuy Volcanic Section

open access: yesGeosciences, 2020
The Siberian Traps Large Igneous Provinces (LIP) emplacement is considered as one of possible triggers for the end-Permian global biotic crisis. However, relative timing of the onset of extinction and the main phase of the magmatic activity are not yet ...

Comparative characteristics of diamonds from areas with a high density of kimberlite bodies

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2023
Background. This paper presents a comparative study into diamonds from kimberlite bodies of the Verkhnemunsky field (Zapolyarnaya, Novinka, Komsomolskaya-Magnitnaya and Poiskovaya), the results of which allow these minerals to be distinguished from those
