This paper presents the reconstruction of the architecture of the lithospheric mantle, including its thermal state and thickness, as well as the scale and efficiency of its sampling by four kimberlites from the Arkhangelsk diamondiferous province: Ar

A diamond plate cut out of a transparent, colorless octahedral diamond crystal of gem quality, with a small chromite inclusion in the core, sampled from the XXIII CPSU Congress kimberlite (Yakutia, Mirny kimberlite field, vicinities of Mirny city), h

Crystalline continental crust of the northern East European platform, particularly within the Arkhangelsk diamondiferous province (ADP), is covered by sedimentary rocks, and no direct samples are available. Scarce data on the age and evolution of con

We showed the effectiveness of the various existing methods applied for the determination of the diamond prospectivity of kimberlite pipes based on the composition of garnets on the examples of high-grade diamond-bearing kimberlite pipes V. Grib and

Sulfide inclusions in Neoproterozoic West African diamonds have revealed mass-independently fractionated sulfur isotopes in them [Smit et.al., 2019]. This feature is a sign of Archean surface changes traced in the mantle. Here we present an S isotope
