摘要/Abstract

摘要： 通过分析利用声波时差资料计算地层剥蚀量的方法原理及其适用条件,认为该方法能够用于计算鄂尔多斯盆地早白垩世以来遭剥蚀地层的厚度。计算结果表明,盆地剥蚀量较大的地区在神木、榆林、佳县等东部地带,剥蚀量可在1 400 m 之上,由东往西剥蚀量逐渐降低,至环县、镇远等盆地西部地区,地层剥蚀量最低,仅在400 m 左右,反映出鄂尔多斯盆地的后期改造具东部强西部弱、边缘强内部弱的特点。

Abstract: By analyzing the principle of the method for estimating the denudation thickness according to interval transit time information and its applicable condition, it is recognized that the method can be used to estimate the denuded thickness after the Early Cretaceous in Ordos basin. The estimation result shows that the gradual denudation decreases from east to west: in eastern areas such as Shenmu, Yulin and Jiaxian whose strata had been denuded over 1 400 m; while in western areas such as Huanxian and Zhenyuan whose strata had been denuded about 400 m. It reflects that the late reconstruction of this basin is characterized by the strong in the eastern and boundary areas and the weak in the western and inner areas.

Key words: Ordos basin, interval transit time, mudstone compaction, strata denudation, Early Cretaceous
