| Abstract: | The Dagougu gold deposit is a new type of gold deposit discovered in China for the first time, which deposit gold in the cataclastic albite within the ductile-brittle shearzone. The gold mineralization is related to the albitization, pyritization and the cataclastization. The dominant paragenetic association of minerals has been taken as native gold sulfidetectosilicate, associated with the carbonate. The ore deposit belongs to the middle-high temperature,dynamo-hydrothermal reworked type of gold deposit. This deposit is formed underthe condition of the ductile-brittle shear action, kept the Senesis in touch with the alteration,the anatexis and the metasomatism as well as the formation and evolution of Sinian SystemLe Chang Xia metamorphic rock group with higher gold contents. |
