| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
