| 摘 要： | 刘屯金矿床为含金硫化物石英脉型,矿体直接围岩为晚太古代混合花岗岩。区域上建平群大营子组为金的矿源层,金成矿与中生代构造岩浆活动密切相关。含金石英脉(矿脉)严格地受近东西向断裂构造控制。据硫同位素组成证明矿石、围岩、中生代侵入岩具有同一性,为幔源硫。氢氧同位素组成则显示了成矿溶液的多成因特征。矿石中铅同位素为古老的铅体系,与中生代岩体的长石铅属同一源地。通过时矿床成因的探讨,认为是"岩浆热源-混合热液"型复成因金矿床,成矿时代为燕山期。

| Abstract: | Liutun gold deposit belong to auriferous sulfide quartz vein type.Late Archean eonmigmatitic granite is the direct wall rock．In the region， Dayingzi Formation of JianpingGroup is the source bed of gold．Gold mineralization is closely related to Mesozoic tectonicand magmatic activities，Auriferous quartz veins （ore vein） were strictly controlled by faultedstructure trending nearly EW， The S—isotopic Composition present that ore wall rock andMesozoic intrusive rock have the same nature—mantle derived sulfide， Hydrogen and oxygenisotopic compositions show the multiple—origines of ore—forming solution. The lead isotopeof ore belong to ancient lead series，and has the same source with that of feldspar in Mesozoicrock body．Through the discussion on ore deposit genesis，the authors consider that the golddeposit complex genesises type of magmatic hot source and mixture hydrothermalsolution，the metallogenetic epoch was Yanshanian period. |
