MELT INCLUSIONS IN OLIVINE AS A SOURCE OF INFORMATION ON THE COMPOSITION AND EVOLUTION OF DEEP MELTS OF AILLIKITES (ULTRAMAFIC LAMPROPHYRES) OF THE ILBOKICHI UPLIFT, THE SW SIBERIAN PLATFORM

Aillikites are kimberlite-like rocks, important for understanding the composition and processes occurring in mantle. Melt inclusions represent a reliable source of information. The paper provides first results studies (Raman, EDS) on primary secondary melt olivine from Ilbokich uplift aillikites. is close to that parent It was significantly enriched CO 2 , H O, phosphorus titanium. Phlogopite, diopside, dolomite, calcite, apatite, Ti-containing phases (brookite, perovskite, Ti-magnetite) lizardite were identified these inclusions. similarity ratios daughter with aillikite matrix indicates slight change when it rising surface. As inclusions, there wide variations compositions smaller amount silicates, as compared ones. main carbonates, e.g. magnesite alkaline carbonates. In addition, phlogopite, clinopyroxene, halite, pyrrhotite magnetite, graphite discovered. variability might be due silicate-carbonate immiscibility appeared during at pressures <4 GPa.
