By three approaching ways- approach from
seasoned present, morphological genetic series approach, Late Pleistocene
depositional surface approach, this paper analyses, systematises, introduces:
1) System of 06 terraces -low plains levels, 06 sea-levels and their elevations
in Nam Bo plain; 2) 06 morphological genetic series, absolute ages in 8000-6200
y.BP, 5.570±260 to 4.550±220 y.BP , 3760±55 to 2.780±140 y.BP, 2580±70 to
1.600±90 y.BP, 1.590±90 to 290±20 y.BP, 180 y.BP to now; 3) Depressing
-upraising, moving degree of some faults after Late Pleistocene.
