Реферат: | eng: Using the Chiller computer program, we performed modeling of the mechanisms of the joint transport and deposition of Au and Sb from various ore-forming solutions during the formation of Au-Sb deposits. Three models are considered by the example of the Uderei Au-Sb deposit in the Yenisei Ridge: (1) simple cooling (cooling only), (2) iso-enthalpy boiling (P = f(T)), and (3) solution-rock interaction (rock titration model). The behavior of Sb(III) and Au(I) in the system Au-Sb-Fe-Cu-Pb-Zn-As-H2O-Cl-H2S-CO2 under hydrothermal conditions was studied. It is shown that both weakly alkaline (near-neutral) and reduced acidic Feaq2+-enriched low-chloride high-CO2 and high-chloride hydrothermal solutions play a crucial role in the formation of gold parageneses of Au-Sb ores. © 2009.
