On the outcrop of flysch nearby Beilaishi(flying stone), north of Lingshan Island, we recognized the typical structures of slump depletion zone——slump scarps. The flysch there belongs to the upper part of Lingshandao Formation (K1lsd), which is mainly composed of coarse sandstone and pelitic sandstone, embedded with some conglomerate beds. Slump scarps were found in the event deposits——sandstone and pebbly sandstone beds. The pelitic sandstone or silty mudstone beds were cut by the slump surface concaving upward. Slump folds, liquefaction sand dikes and event deposits that are frequently outcropped in the flysch were speculated to be triggered by earthquakes. Attitudes of slump folds and scarps reveal the major slump direction, SWNE, and the minor slump direction, SN. Slump folds and scarps in the same section imply a transformation from pure slump accumulation zone to slump depletion—accumulation zone of this area in the Early Cretaceous. The sand—shale ratio of the upper part of Lingshandao Formation nearby Beilaishi(flying stone) is higher than that of the flysch in the Shipyard outcrop. Besides, many gneissose and quartzitic gravels are found in sandstone beds in the upper part of Lingshandao Formation. Therefore, the remnant basin was in its late stage with water shallowing upward during the sedimentation time.
