摘　　要：通过对区域成矿地质背景的分析,结合瓦勒根金矿的地质特征,初步认为瓦勒根金矿受地层岩性、中酸性岩浆岩和断裂构造的复合控制。隆务河群c岩组2岩段泥质细碎屑岩和碳酸盐岩建造含金背景值较高,是本区金矿形成的主要矿源层;矿体受层间断裂构造控制,层控性及构造控矿明显;区内印支晚期石英闪长岩体、石英斑岩体不仅为成矿作用提供热液,也为本区金成矿提供了深部矿源。Through the analysis on the regional metallogenic geological background and the geological character of the Walegen gold mine,it is believed that the Walegen gold mine is controlled jointly by the stratum rock character,medium acid magma rock and fracture structure. The mud fine clastic rock and carbonate rock in the 2 rock＇ s segment of rock＇ s group c in Longwu river are the main deposit source layer in the rigion gold deposit formation. The ore body is controlled by the fracture structure between the rock layers and it is obvious to control the deposit by the structure and the layer. The quartz diorite and quartz porphyry in the region lndo -china later period provided not only the hydrothermal for gold mineralization, but also the deep deposit souree in the area for gold mine formation.
