This paper 0analyzed the fluid inclusions,micro-thermometry and rare earth elements of the Jinchiling gold deposit in Shandong Province.The objective was to study the property and evolution of the ore-forming fluid of this gold deposit.The result shows that these inclusions are dominated by gas and liquid two-phase ones,with few of liquid phase.The compositions of gas in the inclusions are primarily H2O and CO2.The liquid composition is Na+-K+-Ca2+-Mg2+-Cl--SO2-4,and ore-forming fluid is the mixed fluid of magmatic hydrothermal and meteoric water.The homogenization temperature is 140℃~350℃.The main mineralization of gold occurred in the second and third stages of the evolution when the temperature was 185℃~290℃.And the salinity of fluid inclusions is 7.3% to 8.9%,implying an ore-formation fluid of intermediate-low temperature and low salinity.The REE(rare earth element) analysis shows that the inclusions are characterized by LREE(light rare earth element) enrichment,HREE(heavy rare earth element) deplerion,middle negative Eu anomalies,and slightly right-deviation standardization curves.
