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

On the presence of the postmagmatic stage of diamond formation in kimberlites
Записки Горного института, 2022 On nowadays multiphase and the facies heterogeneity of the formations are distinguished at the study of kimberlite pipes. Most researchers associate the formation of diamonds only with the mantle source.
