莱州湾南岸XZK2钻孔晚更新世以来的沉积环境探讨
Discussion on Depositional Environment of XZK2 Borehole in South Costal Zone of Laizhou Bay since Late Pleistocene
摘要
Abstract
Through study on drilling lithology, sedimentary structures, grain size, magnetic susceptibility and log-ging curve, loose sediments of XZK2 borehole in south coastal zones of Laizhou Bay since late Pleistocene have been divided. Combining with 14 C isotopic age determination, the oxygen isotope stages in deep sea have been di-vided. It is showed that the curve of magnetic susceptibility of sediments and sand content has significant positive correlation. Combining with existing research, it is proved that the ancient environment has experienced in this area three alternating cold and warm since late Pleistocene. Three transgression events which are equivalent to Cangzhou marine transgression transgressive, Xianxian marine transgression transgressive and Huanghua marine transgression have been found in the southwest coast of Laizhou Bay. Through drilling holes study, only Holocene Huanghua transgression can be found, while Cangzhou marine transgression and Xianxian transgression are corresponding with coastal deposition layers.关键词
