Characteristics of the Ore-forming Fluid from the Aiziwangjia-Yuantuan Gold Deposit in Shandong Province and Its Origin
摘要
Abstract
This paper presents analysis of the lithofacies, thermometry and sulfur isotopes of fluid inclusions from the Aiziwangjia-Yuantuan gold de- posit in Shandong Province. The purpose is to study the property, evolution and origin of the ore-forming fluid of this gold deposit. The result shows that these fluid inclusions are mainly gas and fluid two-phase ones. Compositions of liquid inclusions are Na＋ , K＋ , Ca2＋ , Mg2＋ , SOl-, C1- and F-, and those of gas liquid are mainly H2 O, CO2 and CH4. The homogenization temperature of ore-forming fluid ranges from 120℃ to 350℃, and salinity of fluid inclusions is between 4.26% and 8.66%, belonging to the middle-low temperature（ ≤200℃ accounting for 70% ）and low salinity fluid. In Pb isotope values, 206pb/204pb ranges from 16. 217 to 18. 034 207 pb/2O4pb ranges from 15. 180 to 16. 889, 208pb/204pb ranges from 36. 586 to 39. 987, respectively, and δ34S （%0） ranges from -4.7 to ＋4.7. The analysis suggests that these isotopes have a mixed material source from crust and mantle.关键词
