Genesis of the Zhijiadi Ag-Pb-Zn Deposit, Central North China Craton: Constraints from Fluid Inclusions and Stable Isotope Data

Figure 13

Pressure-temperature conditions for the early and main stages in the Zhijiadi deposit. (a) Minimum trapping pressure for the early stage based on isochores of C-type FIs in the quartz and the peak homogenization temperatures. (b) Trapping pressures for the main stage based on intersections of isochores of the minimum and maximum densities from the C- and W-type FIs in fluorite. (c) Model for pressure-temperature evolution of the ore-forming fluids from the early to main stages. Qz, quartz; Sp, sphalerite; Fl, fluorite.
