摘要
The Dongtongyu gold deposit is located in the middle-west part of the Xiaoqinling gold orefield. Gold-bearing quartz veins are controlled by the ductile shear zone. According to the vein types and their crosscutting relationships, mineralization of the Dongtongyu gold deposit can be divided into four stages. The main types of fluid inclusions in vein quartz are CO2-H2O fluid inclusions and aqueous fluid inclusions, with small amounts of pure CO2 fluid inclusions. The main gold mineralization was related to the post-orogenic extension environment, with the evolution characteristics corresponding to the evolution of shear zones.
