Abstract:

Zhenzigou Pb-Zn deposit is a representative one of Qingchengzi Pb-Zn ore field. The deposit mainly occurs in Gaojiayu and Dashiqiao Formation, and is controlled by strata,magmatism, and tectonism with the main ore types being stratiform,stratoid,and veined ore bodies. The deposit experienced three metallogenic episodes such as submarine exhalation,metamorphism or deformation, and hydrothermal superposition. Hydrothermal superposition mineralization played an important role in the formation of the veined ore bodies and the local hydrothermal transformation of stratiform ore bodies. It can be classified into two stages:pyrite-galena-sphalerite-quartz(stage Ⅰ)and pyrite-galena-quartz-calcite(stage Ⅱ). According to the fluid inclusions and C-D-O isotope research, aqueous two-phase is developed in stage I with minor vapor-rich and CO2-bearing three-phase in the quartz fluid inclusions, and the ore-forming fluids are of middle-low temperature,low salinity, and low density CO2-H2O-NaCl system with enrichment of H2O,CO2, CH4, and N2. The δDH2O-SMOW,δ18OH2O-SMOW and δ13C of the fluid inclusions in the quartz are -96.5‰ and -95.4‰,-0.62‰ and 0.04‰, -4.8‰ and -4.4‰ respectively, which shows some characteristics of a fluid mixture of meteoric water and magma water. In stage II, aqueous two-phase fluid inclusions are developed in quartz; and the ore-forming fluids are of the low temperature,low salinity and low density H2O-NaCl system, containing a small amount of CO2, CH4, and N2. The δDH2O-SMOW and δ18OH2O-SMOW of the fluid inclusions in the quartz are -88.4‰--80.0‰ and -7.93‰--5.57‰ respectively, which shows the characteristics of meteoric water with δ13C of -12.6‰--7.9‰, a characteristics of magma water. Based on the above, we can infer that in the early mineralization stage, the ore-forming fluids were the mixture of meteoric water and magmatic water in Yanshan period, and in the late mineralization stage the blending proportion of meteoric water increased.

Key words: Zhenzigou Pb-Zn deposit, superimposed hydrothermal mineralization, fluid inclusion, C-D-O isotope, ore-forming fluids
