大、小兴安岭北部是我国重要的砂金产区，区内岩金矿，点及矿化点众多。该区地处中亚－兴安地槽褶皱区北端，火山、岩浆活动及变质变形作用复杂，其对原生金成矿有明显的控制作用，特别是环状构造及华力西期和燕山期高磁性碱性花岗岩和花岗斑岩，与金矿床的形成有着密切的关系。 Large, Xiaoxing’an Mountains north of China is an important gold-producing area, the area of ​​gold and gold deposits, points and mineralization many. The area is located in the northern end of the Central Asia-Xing’an diagenetic fold zone. The volcanic, magmatic and metamorphic deformation are complex and have significant control over primary gold mineralization. In particular, the ring structure and the high magnetic Alkaline granite and granite porphyry, and the formation of gold deposits are closely related.
