UV-fs-LA-ICP-MS Analysis of CO₂-Rich Fluid Inclusions in a Frozen State: Example from the Dahu Au-Mo Deposit, Xiaoqinling Region, Central China

Figure 5

Fluid compositions of the Dahu deposit compared to other hydrothermal systems. (a) Fluid compositions plotted in K/Na (weight ratio) versus Na + K space. (b) Fluid compositions plotted in Rb/Na (weight ratio) versus Na + K space. (c) Fluid compositions plotted in Rb versus K space. Estimated trapping temperatures for fluid inclusions are shown in brackets. Data for orogenic Au deposit ore fluids are from Yardley et al. [34], Hodge [29], Garofalo et al. [30], and Morales et al. [31], for metamorphic fluids from Marsala et al. [35] and Miron et al. [36], and for magmatic-hydrothermal deposits (i.e., porphyry and intrusion-related deposits) from Ulrich et al. [9], Rusk et al. [37], Klemm et al. [10, 11], Audétat et al. [38], Seo et al. [12], Stefanova et al. [17], and Catchpole et al. [15].
