Section snippets Phases and models. The phase equilibria of the Cu–Pb–Zn system have been reviewed by [18]. The system consists of five disordered solution phases, liquid, fcc, bcc, hcp_A3 and hcp_Zn, and one ordered solution phase, gamma (γ).All these phases are described with the substitutional solution model, including the ordered …

1. Introduction. Skarn systems constitute a major source of the world's Pb, Zn, W, Sn, Fe, Cu, Mo, and Au (Meinert et al., 2003, Chang et al., 2019), and are genetically related to the emplacement of dioritic to granitic plutons in active subduction zones to post-subduction tectonics (Meinert et al., 2005, Sillitoe, 2010).A clear documentation of their …

Cu–Zn is an important binary alloy system. In the interested temperature range from 300 to 1500 K, there are eight phases, liquid, Cu, β, β′, γ, δ, ϵ, and Zn phases. The thermodynamic descriptions of the Cu–Zn system are reassessed using the CALPHAD method. A new description of liquid phase and simplified description of body …

The genesis of the Mount Isa Cu-Pb-Zn system, northern Australia, is highly debated. Three metallogenic models have previously been proposed to explain the close spatial relationship between a world-class Cu and Pb-Zn deposit: (1) ca. 1650 Ma syngenetic Pb-Zn mineralisation that has been re-mobilised and overprinted by ca. 1520 …
