摘　　要：对产于辽宁丹东三股流花岗闪长岩体外围的五龙与四道沟大型金矿床地质、流体包裹体岩相学及测温特征进行对比研究表明,五龙与四道沟金矿床成因存在一定差异。五龙金矿床含金石英脉与四道沟金矿床早期石英脉成矿流体主要来自于三股流岩浆活动,而四道沟矿区主矿化阶段成矿流体来源可能与矿区燕山晚期中酸性脉岩活动有关。A comparative study on characteristics of geology,petrography and microthermometry of fluid inclusions between Wulong and Sidaogou gold deposits surrounding the Sanguliu granodiorite body in Dandong of Liaoning has been carried out.The results show that there were some definite differences in their origin.The ore-forming solutions of the auriferous quartz veins in Wulong gold deposit and the early quartz veins in Sidaogou gold deposit both derived from Sanguliu magmatic activity,while the ore-forming solutions of the major metallogenic stage in Sidaogou gold deposit may be related with the activity of intermediate-acidic dykes in the late stage of the Yanshan movement.
