摘　　要：从断裂构造控制矿床的形成,控制矿体的空间分布、形态、产状,控制金矿化富集规律等 方面论述了桃园金矿床断裂构造控矿规律。揭示该矿床在断裂构造变异部位、主断裂上盘次级构 造特定部位、线形环形断裂构造与中基性岩体叠加形成的容矿圈闭部位通过主断裂导矿次级断裂 容矿方式形成金矿化等富集规律。在研究断裂构造控矿规律的基础上,对桃园金矿床进行了成矿 预测。From the angle of the formation of fracture tectonics ore control deposit,the distribution,morphosis and occurrence state of the orebody,and gold enrichment regularity,the paper expounds the fracture tectonics ore controlling law in Taoyuan gold deposit.The gold formed in the main faults and contained in secondary faults in such regions as fracture tectonics variation,secondary structure in hanging wall of main faults,and ore-containing position deriving from the superimposing of linear,ring faults and basic rock.Based on the ore controlling regularity,mineralizing prognosis is conducted.
