There are many types of gold deposits in China, and the main industrial types are: chronological vein type, fractured zone altered rock type, veinlet disseminated type (granite type), structural altered rock type, iron hat type, volcanic-subvolcanic hydrothermal type, fine-grained disseminated type and so on. Gold deposits mainly occur in altered rock type, chronological vein type and volcanic-subvolcanic hydrothermal type in fracture zone, accounting for about 94% of the total gold reserves.
The most famous gold mine in China is Jiaodong Gold Mine. More than 90% of gold mines are concentrated in Zhaoyuan-Laizhou area, and Linglong gold mine is the main mining area. The mining area has a long mining history. Since the founding of the People's Republic of China, modern mining technology has been introduced and gradually developed, and the gold output once ranked fifth in the world. Also belonging to this type are Jinchangyu Gold Mine in Qianxi County, Hebei Province and Xiaoqinling Gold Mine in western Henan Province.
