dc.description.abstract | As proved earlier, an aqueous fluid in equilibrium with mantle minerals at pressures above 10 kb has a relatively high alkalinity. The stability of hydrosulfide complexes of chalcophile elements in such a solution at relatively low temperatures and pressures results in the high solubility of the corresponding sulfides [2]. Therefore, the hydrosulfide form of ore-component transport in high-density aqueous alkaline fluid is most likely very important, too, at higher temperatures and mantle pressures. To check this postulate, the authors ran tests in a piston-and cylinder apparatus, and were able to determine the concentrations of rock- and ore-forming elements in the fluid when copper and nickel sulfides react with water at 600° and 900°C and 20 kb in the presence of clinopyroxenes, synthesized in the system jadeite70-diopside30-water (Jd0.7-Di0.3). | |
