Abstract:
The northern margin of North China platform is a giant gold metallogenic belt of China.Main controlling factors of gold mineralization are Precambrian cystal basement,regional deep-fracture zones and volcano-magma activities.Late Paleozoic-Mesozoic tectonomagmatic activity is the most important factors.Tectonomagmatic activity-related gold deposit-types,especially the particular ones and new ones,will show their great potential in the future.More following widespread gold deposits will be found in the future prospecting because of their specific property and the short of work:1,epithermal gold deposits (related with granite-porphyry);2.porphyry gold deposits,ore-bodies are hosted in granite-porphyry and granite-plutons;3.gold deposits related with alkaline rocks.
