Genetic comparison between Wulong and Sidaogou gold deposits in Dandong of Liaoning—evidence from fluid inclusions

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.
