摘要: 下活龙盖金矿位于中朝准地台北缘鸭绿江金多金属成矿带中段集安隆起上，是典型的产在古元古界变质岩系中的蚀变岩型金矿.集安群地层是初始矿源层，鸭绿江大断裂及次一级构造是导矿、储矿的有利场所，岩浆侵入构成热动力源.区内矿体受3条蚀变带控制，具尖灭再现、尖灭侧现的特征.通过总结成矿规律，认为蚀变带膨大部位和构造交汇部位是厚富矿体的有利赋存位置.

Abstract: 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.
