利用瞬态瑞雷面波法探测浅层玄武岩三维分布——以沙特Sabkhah Ad Dumathah地区为例
|
摘要
沙特Sabkhah Ad Dumathah地区浅层玄武岩的分布影响着该区钙结岩型铀矿的发育空间和分布范围,然而常规钻探、(电)磁法、重磁法等技术手段,对于该区浅层(约30 m以浅)玄武岩,存在探测难度.本文提出了利用瞬态瑞雷面波法开展浅层玄武岩探查试验研究,首先通过面波数据采集技术的系统试验研究,获取了较适用的面波数据采集方法,其次经过面波资料处理得到用于解释的面波速度映像图,最后基于该处理的三维面波速度映像图,解释了浅层玄武岩的三维分布范围和形态特征,通过与测区内已知钻孔资料进行对比,探测结果与地质认识相吻合.可见本文使用的面波勘探法能够较好地探测浅层玄武岩的三维空间分布规律特征,为今后类似工作提供重要参考和借鉴.
The distribution of shallow basalts in the Sabkhah Ad Dumathah area of Saudi Arabia affects the developmental space and distribution range of the calcium-type uranium deposits in this area. However, there are some difficulties in detecting the shallow basalts in 30 meters depth by the conventional drilling, electromagnetic methods, gravity and magnetic techniques, etc. This paper proposes a shallow basalt exploration test using transient rayleigh wave method. Firstly, through the systematic experimental research of surface wave data acquisition, a suitable surface wave acquisition scheme is obtained, and then the surface wave velocity map is obtained by data processing, and finally based on the processed 3 D surface wave velocity map, the three-dimensional distribution shape and range of shallow basalt is interpreted. By comparing with the known drilling data in the survey area, the detection results are consistent with the geological understanding. It can be seen that the surface wave exploration method used in this paper can better detect the three-dimensional spatial distribution characteristics of shallow basalt,and provide important reference for similar work in the future.
