Marine micropaleontological data of SELXH

The Marine micropaleontological data of the three boreholes from the southeast of the Lixiahe area in northern Jiangsu, China, in the lower Marine deposits of the Site areas, TZ-2012, QD-2013 and KZ-2013, reflect the changes of the sedimentary environment with time (intertidal zone - supratidal zone), and prove that the area experienced the process of regression to the land during this period.中国江苏省北部李溪河地区东南部的三个钻孔（TZ-2012、QD-2013和KZ-2013）所采集的海洋微体古生物学数据，反映了该地区下海相沉积层中沉积环境的变迁（潮间带至潮上带），并证实了该区域在此期间经历了向陆地退化的过程。
