Origin and Evolution of the Ore-Forming Fluids in the Liyuan Gold Deposit, Central North China Craton: Constraints from Fluid Inclusions and H-O-C Isotopic Compositions
Table 1
Summary of the microthermometric data from fluid inclusions trapped in quartz and calcite from the three mineralization stages of the Liyuan gold deposit.
C-type, aqueous-carbonic fluid inclusions; PC-type, pure carbonic fluid inclusions; W-type, aqueous fluid inclusions; , melting temperature of solid CO2; , temperature of CO2-clathrate dissociation; , homogenization temperature of CO2; , ice-melting temperature; , total homogenization temperature; L and V stand for liquid and vapuor to which the fluid inclusions homogenize, respectively. The density of CO2 and bulk inclusions are estimated using the Flincor program [32] and the formula of Bowers and Helgeson [33] for the H2O-CO2-NaCl system.
