【 摘 要 】

All manuscripts must be in English, also the table and figure texts, otherwise we cannot publish your paper. Please keep a second copy of your manuscript in your office. When receiving the paper, we assume that the corresponding authors grant us the copyright to use the paper for the book or journal in question. Should authors use tables or figures from other Publications, they must ask the corresponding publishers to grant them the right to publish this material in their paper. The paper made a descriptive record on the drill core BK1 located at east of BenNiu town and the drill core BK2 located at Tangcun in the Changzhou suburbs by lithologic descriptions, lithofacies, age of stratigraphy, analysis of sporopollen and stratigraphic correlation. Combined with previous research results in the area, we drew conclusions that the two drilling cores revealed the Holocene Rudong formation with the thickness of 2m in the study area, the Upper Pleistocene Gehu formation with the thickness of 22 m and the Upper Pleistocene Kunhan formation with the thickness of 47 m and the Middle Pleistocene Qidong formation with the thickness of 113m and the lower Pleistocene Haimen formation with the thickness of 154m.The two standard boreholes reveal the sedimentary response characteristics of the quaternary sedimentary environment in Changzhou and the sedimentary response characteristics of 4 transgression. There are two depocenter in the northeast in the target area where the Suzhou-Wuxi-Changzhou fault passed. According to the age of Suzhou-Wuxi-Changzhou fault activities, inferring that the fault infected stratum of Qp2q and others on it.
