Abstract
Drawing from our research and an extensive review of publications, we have compiled data from goniometric studies concerning the morphology of mineral inclusions in diamonds sourced from both kimberlites and placers. Specifically, we have examined the morphology of olivine, garnet, and chrome-spinelide inclusions. In the majority of instances, the crystalline shape of these mineral inclusions has been instrumentally confirmed to mirror that of diamonds. The formation of such shapes is attributed to the influence of the negative morphology of diamond crystals, the host mineral, on mineral inclusions. The shape of these inclusions reflects various features of diamond morphology, encompassing simple forms, habits, outlines, and surface topography of faces. Compelling evidence supporting the syngenesis of mineral inclusions with diamond-shaped crystals and the diamonds within which they are found lies in indicators of their simultaneous growth. These indicators include the presence of induction pseudo-edges, pseudo-faces, and pseudo-vertices on inclusion crystals.
期刊介绍:
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
