Paleocurrent of the tidal sand body in Subei coastal plain

Based on analysis of magnetic febric and magnetic relict, the paleocurrents racorded in drilling cores in Subei coastal plain are bidirectional. NE-SW in the northern core and NW-SE in the southern core. The paleacurrent pattern in the area is similar to that of the tidal current system in the South Yellow Sea. So it is inferred that the convergent-divergent tidal current system existed during stage of sand body formation, and they should be radial in plane.
