摘　　要：通过于拉陵灶火金矿床内开展槽探、钻探等基础地质工作,圈定含矿蚀变破碎带3条,金矿体13条;发现金矿体主要赋存于蚀变破碎带中,且严格受断裂控制,岩石具有强碎裂岩化、硅化、黄铁矿化等特征,矿床成因类型为构造蚀变岩型金矿床。Based on the basic geological work, such as trough exploration and drilling in Lalingzaohuo gold deposit, we delineated three altered fracture zones and thirteen gold ore bodies. The gold orebodies mainly occurred in the altered fracture zone, and they are strictly controlled by faults. The fractured rock had strong lithification, silicification, pyritizatio, and the origin types of the ore deposit was tectonic in altered rock type gold deposit.
