早在1962年,中国科学院海洋研究所海岸地貌组在山东半岛北岸东段海岸地貌调查报告中,首先将分布于柳夼、礼村一带山前的红棕色砂层命名为“柳夼红层”。后来,又依据其分布特征和沉积物粒度分析资料等,论述了“柳夼红层”的成因,认为属于海相沉积。1978年,金波、郭旭东又将此红棕色砂质沉积物确定为中—晚更新世的海相沉积。并由此 As early as 1962, the Coastal Geomorphology Group of the Institute of Oceanology, Chinese Academy of Sciences named the reddish brown sand layer distributed in the front of the Liupan and Li Village in the survey report of the coastal landscape in the eastern section of the northern coast of Shandong Peninsula. Later, based on its distribution characteristics and sediment grain size analysis data, the author discussed the genesis of the “Liuban red layer” and considered it to be marine sediments. In 1978, Jin Bo and Guo Xudong identified the reddish brown sandy sediments as mid-late Pleistocene marine sediments. And thus
