Typomorphic features of graphite inclusions in diamond: experimental data [PDF]
Russian Geology and Geophysics, 2015 Abstract Diamond crystals with graphite inclusions synthesized during the experimental modeling of natural diamond formation in chloride and carbonate systems under mantle PT-conditions were studied to elucidate the specifics of the protogenetic graphite inclusions.

Diamonds from low-grade kimberlite
Руды и металлы, 2022 Based on exploration and sampling work on the Siberian platform (SP) the uneven diamond content of various diatremes was established. During the exploration apart from the pipes with high or medium content of a useful component also the diatremes with ...

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

Typomorphic features of diamonds from ancient sedimentary thick layers of platforms’ central parts
Мінеральні ресурси України, 2020 Basing on generalization of large actual material on complex investigation of diamond its characteristic in Upper Paleozoic and Mesozoic sedimentary thick layers of the Siberian platform is provided. Special attention is paid to the Central-Siberian sub-province, where it is convincingly shown that the area of development of individual diamond macro ...
