摘　　要：通过分析桐木铜多金属成矿亚带地质地球物理特征可知,研究区磁场特征较为简单,为平稳的弱磁场区,放射性场则呈现出明显的平行条带状特征,与断裂及地层走向相同。对重点异常开展了地物化综合研究,并以此为基础建立了该成矿亚带地质地球物理地球化学找矿标志,区内HF35等重点放射性局部异常具较大寻找铜多金属矿的潜力。成矿亚带受构造和围岩双重控制作用明显,但主要受桐木区域性大断裂控制,大断裂及次级构造所形成的构造破碎带对成矿最为有利。Analysis of geological-geophysical characteristics of Tongmu sub-Cu-polymetallic ore belt of the west side of Dayaoshan Mountain shows simple,characteristics of magnetic field,a stable weak magnetic field and a radioactive field characterized by clearly parallel bands.The bands trend in the same direction of the faults and strata.Comprehensive study is carried on the key anomalies and prospecting geological-geophysical-geochemical marks are established on basis of the study.Local anomalies within the key anomaly,such as HF35 are potential for prospecting Cu-polymetallic ore.The sub-ore belt is both controlled by structure and wall rock but mainly controlled by the regionally big Tongmu fault.The structurally clastic zones related to the big fault and its sub-faults are the favorable sites of ore.
