Resumo

The samples of monosulfide solid solution (Mss) based on α-NiS and FeS were obtained at P = 7.0 GPa and T = 900–1500°C with previously synthesized sulfide compounds by solid-phase method at T = 400–600°C. The structural and textural characteristics of the samples were identified and the unit cell parameters of the investigated sulfides were determined. Based on the revealed features and chemical compositions a fragment of the phase diagram in the Fe–Ni–S system with the assumed solidus and liquidus lines was constructed. According to the obtained results, in the studied range of compositions a continuous series of solid solutions of minerals (Mss) is formed. The evolution of the composition of monosulfide solid solution and corresponding sulfide melt under diamond formation conditions as a function of temperature change was traced. We have preliminary estimated the maximum Ni content in sulfide melts (up to 58 wt. %), which may crystallize the minerals found in inclusions in natural diamonds of the peridotite association.
