| 摘 要： | 本文简要介绍了阿尔金成矿带近年来发现的主要金属矿床的地质地球化学特征,研究了矿床S、Pb、H、O等同位素地球化学,测定了部分矿床的流体包裹体成分和温度,并在此基础上讨论了矿床的成因。该带主要矿床类型有火山喷流块状硫化物铅锌铜多金属矿床(喀腊大湾)、叠加改造型铅锌铜多金属矿床(更新沟和拉配泉)、斑岩型铜矿床(索拉克)、卡林型金矿床(祥云和盘龙沟)、与火山作用有关的浅成低温热液金矿床(采石沟)、韧性剪切带型金矿床(红柳沟)、与钾长花岗岩侵入作用有关的热液金矿床(大平沟)等。

| Abstract: | This paper deals with the geological and geochemical characteristics of the main metallic deposits in Altyn metallogenic belt.Based on the studies on geochemistry of S,Pb,H,O isotopes and the fluid inclusions including compositions,temperature and salinity,the metallogeneses of the deposits are discussed.Main deposit types in this area are as follows: VMS-type of Pb-Zn-Cu poly-metallic deposits,superimposed and reformed deposits(e.g.Kaladawan),Carlin-type of gold deposits(e.g.Xiangyun and Panlonggou),epithermal gold deposits related to volcanic activities(e.g.Caishigou),disseminated gold deposits controlled by ductile shear zone(e.g.Hongliugou),hydrothermal gold deposits related potassic granite intrusion(e.g.Dapinggou). |
