Magnetic fabric characteristics of late Quaternary strata in Shanghai area

The result of measurements and analyses on magnetic fabrics data for the late Quaternary core at Caoyangxincun in Shanghai shows that abrupt changes of magnetic fabric curves coincide with the boundaries between the marine strata and underlying stiff clay. Littoral, neritic, subtidal and tidal fiat facies in the marine strata have distinct magnetic fabric characteristics. The curves of the parameters, K, P, L, q, display clear boundaries between various facies, which could serve as a new method for the stratigraphic subdivision and correlation.
