摘要: 箕状断陷是鲁西隆起和济阳坳陷最主要的构造样式。利用野外剖面观察、室内地质剖面分析、地震剖面分析以及裂变径迹年代学等方法对鲁西隆起和济阳坳陷箕状断陷的形成时代进行了探讨。结果表明,鲁西隆起的箕状断陷发育在本区沉积的最新地层官庄组沉积之后(即始新世以来),与距今42~38Ma发生的蒙山抬升事件有关。济阳坳陷的箕状断陷形成时代为沙三段至东营组沉积时期,大约为距今42~24.6Ma。由此可见,鲁西隆起和济阳坳陷箕状断陷的形成时代一致,均为距今42~24.6Ma。

Abstract: The dustpan fault depression is the most important tectonic style in Luxi Uplift and Jiyang Depression. The field profile observation, indoor geological profile analysis, seismic profile analysis and the fission-track dating were used to study the formation age of dustpan fault depression. The results showed that the dustpan fault depression of Luxi Uplift was developed after deposition of Guanzhuang Formation (since the Eocene) and related with the Mengshan Uplift incident generated in the period from 42 Ma to 38 Ma before present. The dustpan fault depression in Jiyang Depression was formed after deposition of Shahejie Formation and before deposition of Dongying Formation in the period of about 42 Ma to 24.6Ma before present. Therefore, the dustpan fault depression in Luxi Uplift and Jiyang Depression were formed in the period of 42 Ma to 24.6 Ma before present.

Key words: Luxi Uplift, Jiyang Depression, dustpan fault depression, formation age, seismic profile analysis, fission-track dating
