Abstract:

Infrared micro-thermometry technique is efficient to study fluid inclusions in opaque-translucent minerals by connecting the infrared microscopy with cooling-heating table. The sphalerite-hosted fluid inclusions in Huize super-large Zn-Pb-(Ag-Ge) deposit have been studied by this technique. There are six types of sphalerite-hosted fluid inclusions, including pure gaseous inclusions(V), pure liquid inclusions(L), gas-aqueous inclusions with aqueous-rich(L+V), gas-aqueous inclusions with rich gas(L+V), three-phase inclusions containing a daughter(L+V+S), and LCO2+LH2O+VCO2 three-phase inclusions. Two types of gas-aqueous fluid inclusions with rich liquid and pure liquid(L) can be only seen in calcite. The homogenous temperature of sphalerite-hosted fluid inclusions ranges from 100 to 364℃, in which two distinct temperature sectors are 150-221℃ and 320-364℃, with the average capture temperature 232℃. The salinity of sphalerite-hosted fluid inclusions has three distinct sectors of 1.1%-5.0%, 5.0%-11.0%,and 12.0%-18.0%. The homogenous temperatures of sphalerite-hosted fluid inclusions of different mineralization stages reflect the evolution of the ore-forming fluids in the whole process; while the calcite-hosted fluid inclusions indicate the middle and late mineralization stages of the ore-forming fluids. Comparing with the paragenetic gangue mineral, the homogenous temperatures of fluid inclusions in sphalerite are higher, which indicates that sphalerite-hosed fluid inclusions carry more information of ore-forming fluids. From early to late mineralization stages, ore-forming fluids might have experienced the evolution of medium-high temperature and medium salinity →medium-low temperature and medium salinity →medium-low temperature and medium-low salinity. The capture temperature of fluid inclusions reflects that ore-forming fluids of early stage occurred in medium-high temperature. The features further confirm that different from the typical MVT Zn-Pb deposit, Huize deposit is not a low-temperature deposit. The infrared micro-thermometry technique has provided an ideal method to study the p-T-x conditions of ore-forming fluids and the genesis of Zn-Pb deposits in the northeast Yunnan Province.

Key words: fluid inclusions in sphalerite, infrared micro-thermometry, genesis of HZT-type deposit, Huize super-large Ge-rich zinc-lead deposit, northeastern Yunnan deposit concentration district
