| Abstract: | Based on the geological environments and mineralization of the area north to Chifeng of Inner Mongolia, two kinds of mineralizations are recognized, including tin polymetal mineralization and copper polymetal mineralization respectively. Therefore, two ore belts, the Huanggangliang-Haobugao tin polymetal ore belt in the west and the Aoerge-Haolaibao copper polymetal ore belt in the east are distinguished. These two ore belts are quite different both in type of mineralization and in genesis caused by different geological setting. In the west, the mineralization of porphyry series formed in Yanshanian movement are characterized by the Dajing deposit with a tin copper silver lead zin mineralization, which were formed during the Yanshanian subvolcanic hydrothermal activities, while in the east, the mineralization is characterized by the Bianbianshan porphyry copper gold zinc lead mineralization, which is closely related to the intrusions of some acid intermediate subvolcanic stocks. The recognition of these metallogenic belts has great significance for the further mineral resources exploration in this region. |
