DISCUSSION ON THE GEOLOGY AND GENESIS OF DAGOUGR-TYPE GOLD DEPOSITS IN NORTHERN GUANGDONG PROVINCE

The Dagougu gold ore is a new type gold deposit discovered in China for the first time, which deposited gold in the cataclastic albite within the ductile-brittle shear zone. The gold mineralization is related to the albitization, the pyritization and the cataclasitization, The orebody is jointly controlled by the ductile-brittle shear zone, the albitization, the pyritization and the metamorphic rock of Caledonian period low greenschist facies. The paragenetic association of mineral has been taken the native gold-the metal sulfide-the tectosilicate as dominant factor and associated with the carbonate. The ore deposit belongs to the middle-high temperature dynamo-hydrothermal reform type gold deposit, kept the genesis in touch with the alteration, the anatexis and the metasomatism that the Sinian System Le Chang Xia group metamorphic rock with higher gold content was formed and evolved by the ductile-brittle shear action.
