The determination of ancient ages of zircons in dunites from the orogenic regions and central-type platform massifs raised a number of issues: 1) the equilibrium of zircon with dunite material and, as a result, the possibility of determining the age

The results of study of phase equilibria in the MgO–SiO2–ZrO2 system at 1450–1550°C are reported. The studied system contains two eutectic points and six fields: (I) MgSiO3 + SiO2; (II) MgSiO3 + ZrO2; (III) ZrSiO4 + SiO2; (IV) MgSiO3 + Mg2SiO4

We report a process for the preparation of ultrafine silicon carbide powder in a self-contained protective atmosphere. The protective atmosphere is ensured by the silicon monoxide released during the carbothermal synthesis. A reactor design is propos

The problem of the U–Pb age of zircon crystals from ultrabasic rocks is discussed in this paper. It is shown that the assumption on the xenogenic nature of zircon crystals in dunite is not consistent with the petrographic and experimental data. The

The results of experimental studies of interaction between zircon crystals and dunite at 1400–1550°C are given. At 1400°C no interaction of zircon with dunite takes place. At higher temperatures zircon interacts with olivine forming eutectoid mix
