| 中文摘要: |
| 由于地表的浅覆盖,给区域地质填图带来一定的困难.文章从磁法测量与放射性测量对于不同岩性的磁化率与放射性含量差异出发,讨论了不同填图单元的放射性测量曲线与磁测曲线的形态符合关系,并通过实测剖面的分析,得到大兴安岭火成岩区不同填图单元磁测异常形态与放射性测量异常形态的符合关系,可用来快速确定浅覆盖区下填图单元边界,从而减小槽探工程. |
| 英文摘要: |
| Because of shallow overburden, it was difficult to delimit boundary between mapping units in regional geological mapping. This paper discusses different data corresponding relationship between magnetic survey and radioactive survey for different mapping unit on the base of difference on rock magnetization and radioactive element content. Meanwhile by analysis of field measure profile, the results show the corresponding relationship between magnetic anomaly curve and radioactive anomaly curve for different mapping units in the Daxing'anling igneous province. It is suggested that this method can apply for delimiting a boundary line between mapping units quickly in order to reduce the trenching project. |
