摘要
An analysis of seismic data obtained through a cable route survey starting from the Qingdao coast to offshore has determined nine seismic units since Late Pleistocene. Correlation of the seismic data with Borehole Hj2 confirms three eustatic events that occurred during the Late Quaternary and formed terrestrial units 2, 5 and 7. At the low sea level stage, paleo rivers highly developed, eroded previous strata, formed paleo valley, and left materials.
