| 中文摘要: |
| 甘肃梧桐井铁铜多金属矿区已发现的铁铜矿体主要产于大理岩和斜长花岗岩接触带上，严格受北东向断裂控制。在该矿区实施了1:10000地面高精度磁测和1:10000激电中梯测量工作。综合研究物探异常发现，不论磁异常还是激电异常，其展布方向均与矿区地层、构造走向基本一致，与地质构造关系密切，具有重要的找矿意义。圈定的磁异常和激电异常都是该区勘查铁、铜矿的直接找矿标志。激电异常和磁异常同时出现，特别是当激电异常处于磁异常强梯度带上时应高度重视。本次研究利用综合物探方法，结合矿区地质特征，进行了成矿预测，有效地指导了地质找矿工作，取得了较好的勘查效果。 |
| 英文摘要: |
| Iron and copper ore bodies discovered in the Wutongjing iron and copper polymetallic mining area occur on the contact belt of marble and plagioclase granite, which are strictly controlled by NE-trending faults. The 1:1 million ground high-precision magnetic survey and 1:1 million IP measurement were carried out in the mining area. It was found that the magnetic and IP anomaly distribution directions are basically consistent with the strata and structural trends of the mining area, closely related to the geological structure, and has important significance for prospecting. The magnetic anomalies and IP anomalies are both direct prospecting marks in exploration of iron or copper. Much attention should be paid that IP anomalies lie on the intense gradient belts of magnetic anomalies. Using integrated geophysical methods, combining with the features of mining area geology, the metallogenic prediction has been carried out, which has effectively guided the geological prospecting work and achieved good results. |
