| 摘 要： | 赣东北地区是我国重要的铜铅锌金银多金属矿集区,银山铅锌(银)铜(金)多金属矿床是赣东北地区一个重要的大型次火山热液型多金属矿床。银山铅锌矿发育有闪锌矿-方铅矿-石英脉,前人研究认为金属矿物与脉石矿物为伴生关系,但是没有强调它们的成因上的联系。本次研究开展了矿石矿物中闪锌矿和伴生脉石矿物中石英的流体包裹体对比研究。通过详细的岩相学观察、显微测温、显微激光拉曼探针工作,对伴生石英脉和闪锌矿内原生包裹体,伴生石英脉中的晚期微细石英脉和闪锌矿内部次生包裹体进行流体特征的对比研究。研究结果显示,伴生石英脉原生流体包裹体比闪锌矿的原生包裹体的平均均一温度高约30℃,明显富集CH4、N2、CH4、CO2等挥发份,伴生石英脉中的晚期微细石英脉流体包裹体比闪锌矿次生包裹体的平均均一温度高23℃。闪锌矿原生包裹体与想伴生的早期石英脉在平均均一温度有所差别,气相成分差异明显,均表明矿石矿物与伴生脉石矿物可能形成于不同的地质环境,具有不同的温度和流体成分。 |

| Abstract: | Dexing district of Northeast Jiangxi Province is one of the large ore concentrating areas in the eastern metallogenic belt of China.Yinshan lead-zinc-copper(gold)polymetallic deposit is one of large subvolcanic hydrothermal ore deposit,China.Mineralization consists of quartz,sphalrite,galena,and various amounts of base metal sulfides in veins.Texture evidence shows that the ore minerals(e.g.sphalerite and galena)are spatially associated with quartz veins and veinlets.Previous studies of fluid inclusions mai... |
