摘要
On the base of studies on the landforms and Quaternary deposits through detailed geologic mapping and borehole data, the authors probed into the tectonic activities of the Dongting Basin and its adjacent areas. The Dongting Basin entered into a depressional phase since late Middle Pleistocene. The basin rose and were denuded in late Middle Pleistocene, while there occurred tectonic tilt on the east and west margine of the basin,and folds in Quaternary deposits were formed in part areas. Main body of the basin subsided for depression and received deposits during Late Pleistoncene-Holocene, while there existed clear rise in part areas around the basin. These tectonic activities in different periods can be interpreted by deep matter transfer of the Dongting Basin and its periphery, and by movement of the plate-scale material and compression.
