摘要
The Xiahuolonggai gold deposit, tectonically located in Ji’an uplift in the middle of the Yalu River polymetallic mineralization belt of Sino-Korean platform, is of typical altered rock-type occurring in the Paleoproterozoic metamorphic rocks. The Ji’an group is the primary source bed. The Yalu River large fault and its secondary structures behave as the passageways and houses for the ore fluid. The magmatic intrusion supplies thermodynamic source. The orebodies are controlled by three alteration belts, with characters of pinching out and reappearing. Based on the study of the metallogenic regularity, it is suggested that the expanding alteration belts and structural intersections are favorable positions for thick and rich orebodies.
