摘要
银川盆地作为鄂尔多斯西缘一个大型的拉张型断陷盆地,沉积了巨厚的第四系,也是一个巨大的富水盆地。为了研究银川盆地第四系分布特征,通过盆地内布设完成的5条音频大地电磁测深剖面以及35条高频大地电磁测深剖面,采用BOSTIK反演技术,对盆地第四系分布特征进行了研究,解译了第四系厚度变化及岩性分布特点。
The Yinchuan basin,which is a large tectonic faulted basin in the western edge of Ordos,deposits a thick Quaternary system and is a huge rich basin.To study the Quaternary distribution characteristics of the Yinchuan basin,the distribution characteristics of the Quaternary system in the basin are carried out by using BOSTIK inversion technique through the five audio magnetotelluric sounding sections and 35 high-frequency magnetotelluric sounding sections.The basin Research gives a clear interpretation of the Quaternary thickness changes and lithological distribution characteristics.
