| 摘 要： | 结合研究区雷州半岛的实际地质情况，通过在陆上布置磁道，近岸的浅海-潮间带海水中布置电道，实现了海陆电场和磁场分离同步采集的大地电磁勘探，填补了海陆地震空白带．通过建立针对性的地电模型，利用正演模拟方法校正了海水对陆地测点的畸变效应影响，并通过大地电磁二维反演以及重力和磁力数据的正反演计算，进行了综合地质地球物理解释，证明了海陆联测数据的采集、处理和解释效果．

| Abstract: | In accordance with the practical geological situation of the studied area in Leizhou peninsula,the land-sea synchronous magnetotelluric observation was fulfilled by using separated electrical channels in the neritic zone and magnetic channels on the nearby land,which fills the blank of seismic(prospecting) in the neritic zones and the land between them.The distortion effects on the land magnetotell-uric sounding(MT) sites resulted from the sea-water were also corrected by using forward modeling methods based on the typical geo-electrical model.Integrated geological and geophysical interpretation was proposed on the basis of 2-D MT inversion and gravity & magnetic inversion results,which proves fruitful the collecting,processing and interpretation of the land-sea synchronously observed MT data. |
