Abstract: The depth of shallow-buried paleochannels in Lubei（North Shandong Province）Plain are 8—60 meters underground.The paleochannels can be divided into three major paleochannel belts,which stretch parallelly from southwest to northeast.They are generally 5—15kin wide, the widest section reaches 20km.Sediments of the paleochannels are mainly composed of fine sand,silt or medium sand,usually 10—20 meters thick,the thickest 40 meters.The floor levels of the shallow-buried paleochannels consist of brown-yellow sandy clay or clay,the top levels grey sandy clay,clayey shad and mud. According to the characteristics of the paleochannel sedimental structure and the synthetic analysis of granularity,mineral and sporepollen data,the shallow-buried paleochannels can be divided into two sedimental stages.¹⁴C dating shows that paleochannels in the first stage in the lower sedimental cycle was formed about 25000—9500 years B.P.They are,the river traces from the last period of the Late Pleistocene to the early period of the Holocene.The sediments in the second stage was formed 9500—4100 years B.P.,the early-middle period of the Holocene.
