| 中文摘要: |
| 文章通过对龙首山铀成矿带的主要控矿构造——绿草沟断裂(F3)进行音频大地电磁测量,研究了该断裂电性结构,结合区内地质情况与0号勘探线地质剖面资料进行对比分析,推断了断裂的位置、产状以及深部延伸特征。总结了绿草沟断裂矿化电性特征,主要表现为线性视电阻率异常低阻带,近东西走向,倾向北。预测L02线绿草沟断裂与次级断裂深部交汇部位,可以作为下一步找矿工作的重点区。 |
| 英文摘要: |
| The audio magnetotelluric measurement for the main ore-controlling structure, i.e., Lücaogou Fracture (F3) in the Longshoushan uranium metallogenic belt was conducted for the purpose of studying its electrical structure. In combination with the comparative analysis of geological conditions in the area and the geological section data of No.0 section line, the position, attitude and deep extension characteristics of the fault were interpreted. The electrical characteristics of mineralized Lücaogou fracture were summarized. The apparent resistivity along the fault presents linear low resistivity anomaly, and the fracture extends generally nearly EW direction and dips north. It is predicted that the jointed position of Lücaogou fracture along L2 section line and secondary fracture will be the main target area for the next step prospecting. |
