| 摘 要： | 辽南营口地区的猫岭金矿、黄家营子金矿、金厂沟金矿、隈子金矿等,金矿矿区内的矿石铅和中生代似斑状黑云母二长花岗岩的钾长石铅都是二个阶段的异常铅,二者的铅同位素组成近于一致,其中猫岭金矿的铅同位素组成与元古宙盖县组变质岩的铅同位素组成近于一致,表明成矿物质来自中生代似斑状黑云母二长花岗岩和盖县组变质岩。由氢氧同位素组成研究结果看,这些金矿的成矿热液主要来自于花岗岩浆热液,混有少量的大气降水。

| Abstract: | In Maoling gold deposit，Huangjayingzi gold deposit，Jinchanggou gold deposit and Waizigold deposit in southern Liaoning，the ore lead and K—feldspar lead of Mesozoic biotiteadamellite porphyritic—like are two—stage anomalous lead． The lead isotope compositions ofboth show identical value approximately．The lead isotope compositions from Maoling golddeposit is approximately consistent with that of the metamorphic rocks of Proterozoic Gaixi-an group，This indicates that the mineralization interial was derived from Mesozoic porphyrit-ic—like biotite adamellite and the metamorphic rocks of Gaixian group．A ccording to studingresult of hydrogen and oxygen isotope compositions，the mineralization hydrothermal solutionof gold deposits was derived from mainly the hydrothermal solution of granite magma ，andmixed with a little meteoric water. |
