| 摘 要： | 刘屯金矿床为含金硫化物－石英脉型，以其品位富、埋藏浅为特点，本文通过矿床的稳定同位素研究认为，矿石硫同位素组成与围岩硫相似，具幔源岩浆成因特征；矿石氢氧同位素组成显示出成矿溶液具备多成因的特点，锶、铅同位素组成具壳幔混合成因，以此推断矿床为岩浆热源－混合热液成因。

| Abstract: | Liutun gold deposit,a quartz vein type deposit,is characterized by its high grade,shallow buried depth.Having studied stable isotopes of the deposit the authors conclude the following:the S isotope composition of ores is similar to that of the wall rock indicating the mantle-sourced magma origin;H and O isotope compositions of ores show the polygenetic origin of ore-forming solution;and Sr and Pb isotope compositions indicate the mantle and lower crust source.Based on the above data,the genesis of the deposit considers to be of magma-mixed hydrothermal type. |
