Abstract

[Discovery of diamonds with primary inclusions of ultrabasic ferropericlase and bridgmanite as well as basic magnesiowustite and stishovite became a prime familiarity with lower mantle minerals originated in multicomponent diamond-parental melts. The mineralogical similarity of diamond-hosted inclusions and experimental minerals of pyrolitic origin can be disseminated to the native lower mantle mineralogy. It is symptomatic that diamond-hosted ultrabasic and basic mineral assemblages were determined. These observations can indicate the compositional evolution of both diamond-parental melts and native lower mantle magmas. At the same time, physico-chemical mechanisms of ultrabasic-basic evolution as native magmas so diamond-producing melts may be revealed only with the use of physico-chemical experiments. ]
