| 摘 要： | 郯庐断裂带东地堑边界断层在断裂带演化过程和现今构造格局中都是重要断层,对该边界断层的第四纪活动性研究有助于了解郯庐断裂带的演化历史和地震活动性,而有关该边界断层第四纪活动性研究较少且至今尚无定论。本文通过浅层地震勘探和钻孔联合剖面相结合的方法,针对郯庐断裂带江苏段东地堑两边界断层开展系统的断层第四纪活动性研究,结果显示,昌邑-大店断裂(F_1)第四纪以来未见构造运动证据,白芬子-浮来山断裂(F_2)在第四纪早期曾发生有关活动,晚更新世以来未见活动迹象。

| Abstract: | The boundary fault of eastern graben,the Tan-Lu Fault Zone,is the main boundary fault which plays an important role in the evolution of the fault zone and present structural framework. The research on the Quaternary activity of the boundary fault of the eastern graben is helpful to understand evolutionary history and seismicity of the Tan-Lu Fault Zone. However,the study on the two boundary fault is rare and inclusive. Based on shallow seismic exploration and composite drilling section,this paper systematically researches the Quaternary activity of the boundary fault of the eastern graben in the Jiangsu segment,the Tan-Lu Fault Zone. The result reveals that there is no evidence of tectonic movement since the Quaternary period along the Changyi-Dadian Fault(F1). Nevertheless,Baifenzi-Fulaishan Fault(F2)exists in the tectonic movement during the early Quaternary period. |
