摘　　要：大瑶山金矿成矿带位于广西东部，金矿化主要产于寒武系浅变质砂页岩、绢云母板岩中，加里东期中酸性岩浆岩与成矿有关。金矿床（点）主要为构造破碎带蚀变岩型。金矿体受断裂构造的直接控制。成矿带内金矿受区域网格状构造控制，金矿化表现出“三层楼”成矿规律。区内金的资源量预测为50～100t。Dayaoshan Au ore belt lies in the east Guangxi province. Mineralization occurs in Cambrian metamorphic sandy shale and sericit slate and is related to Calidonian intermediate-acidic magmatic rocks. The deposits belong to altered cataclastic rock type. Ore bedies are directly controled by fractures. Au deposit distribution in the ore belt is controled by regional grids and mineralization occurs in 3 horizons.
