| 摘 要： | 青城子矿田是辽宁东部重要的金多金属矿田，成矿作用复杂.选择白云金矿和小佟家堡子金矿进行了硫同位素和氢氧同位素研究.结果显示矿田内小佟家堡子等金矿硫同位素含量为1.87‰~16‰，无明显的塔式分布；白云金矿的硫同位素含量为-10.3‰~+1.9‰.氢氧同位素测试结果显示白云金矿中石英δD含量为-108.3‰~-74‰，δ18O含量为8‰~15.9‰；而小佟家堡子等金矿的石英氢氧同位素分布则较为分散.综合分析认为，小佟家堡子金矿代表了早期金成矿，与变质作用有关；白云金矿代表了晚期金成矿作用；矿田内层状铅锌矿与小佟家堡子等金矿可能是同期成矿事件.

| Abstract: | The Qingchengzi orefield in eastern Liaoning Province is an important gold polymetallic orefield with complex mineralization.The Baiyun and Xiaotongjiapuzi gold deposits are chosen to study the S-D-O isotopes.The results show that the S isotope content in Xiaotongjiapuzi gold deposit is 1.87‰-16‰,without distinct tower distribution,while that in Baiyun gold deposit ranges from-10.3‰to+1.9‰.The D-O isotope test results indicate that theδD content is from-108.3‰to-74‰,and theδ18O content is 8‰-15.9‰in the quartz of Baiyun gold deposit.The D-O isotopes of quartz in Xiaotongjiapuzi gold deposit is dispersely distributed.According to the comprehensive analysis,it is believed that Xiaotongjiapuzi gold deposit represents the early-stage mineralization,related to metamorphism,and Baiyun gold deposit represents the late-stage mineralization.The mineralization of stratiform Pb-Zn deposit and Xiaotongjiabaozi gold deposit in the orefield might occur in the same period. |
