    河北雄县全新世中期海侵地层的发现

    The discovery of Mid-Holocene transgressive strata in Xiongxian County, Hebei Province

    • 摘要: 渤海湾全新世海侵是第四纪晚期全球气候变化的重要事件,以往研究表明渤海湾西岸全新世海侵已经深入到文安县。本次研究在文安县西北30km的雄县15BZ02剖面第8层底部灰褐色粉砂中发现大量缢蛏新种,壳体呈斜交或垂直层面产出,反映了潮间带中下部的内湾、河口环境。同时,在该层段发现了海相介形虫Tanella opima。由此推断,渤海湾西岸海侵于全新世中期(6970~6670cal a BP)达到最大范围,海水曾经到达雄县北。

       

      Abstract: Holocene transgression in the Gulf of Bohai Sea was an important event of global climate change in the Late Quaternary. Previous studies have shown that Holocene transgression on the west coast of the Bohai Bay has penetrated into Wen'an County. The authors discovered a new species of genus Sinonovacula in 8th layer along the 15BZ02 profile in Xiongxian County of Hebei Province, 30 kilometers east of Wen'an County. These new species are perpendicular or oblique to the formation, and inhabited in the medial tide and low tide of the intertidal zone of the estuary. Besides, marine-ostracoda Tanella opima were discovered in this layer, which shows that sea water transgressed into Xiongxian areanearly 6970~6670cal a BP in Middle Holocene.
